Google patent filing would identify faces in videos, spot the You in YouTube

Google patent filing would identify faces in videos, spot the You in YouTube

Face detection is a common sight in still photography, but it's a rarity in video outside of certain research projects. Google may be keen to take some of the mystery out of those clips through a just-published patent application: its technique uses video frames to generate clusters of face representations that are attached to a given person. By knowing what a subject looks like from various angles, Google could then attach a name to a face whenever it shows up in a clip, even at different angles and in strange lighting conditions. The most obvious purpose would be to give YouTube viewers a Flickr-like option to tag people in videos, but it could also be used to spot people in augmented reality apps and get their details -- imagine never being at a loss for information about a new friend as long as you're wearing Project Glass. As a patent, it's not a definitive roadmap for where Google is going with any of its properties, but it could be a clue as to the search giant's thinking. Don't be surprised if YouTube can eventually prove that a Google+ friend really did streak across the stage at a concert.

Photo tips for a sparkling Fourth of July

23 hrs.

Heading out with the family for July 4th fireworks celebrations is a time-honored tradition. And, if you're like me, you enjoy capturing those memories in pictures. But photographing fireworks with no camera shake and proper exposure is difficult, unless you know these simple tricks:

1. Use a tripod
When you take picture of fireworks, the camera needs to hold the shutter open long enough to ?see? the fireworks. The longer the shutter is open, the more susceptible your photo is to motion blur. So use a tripod to make sure there?s no movement. For open areas, use a stand-alone model with telescoping legs like the Dolica AX620B100 Proline($38.40). A more mobile option is the Joby GorillaPod($12.30), which can wrap around trees and poles or stand up on the ground.

2. Use the ?fireworks? scene mode
Most point-and-shoot cameras have a button or dial with ?SCN? or ?Scene? on it. Otherwise you?ll find it under the ?menu? button. When you put your camera in scene mode, a list of the available modes will pop up on screen. Select the one that looks like a spray of fireworks and/or says "fireworks."

Most cameras sold today have a "fireworks" mode. Some models I recommend include the GE Smart J1470S (an affordable 14MP camera with a 7x lens, $105.29), Nikon Coolpix AW100 (an extremely rugged 16MP camera, $289.95) and the Canon PowerShot S100 (a 12MP camera with a superfast f/2 lens for great low light photography, $363.95).

You can find all of my recommended cameras in our Digital Camera Buying Guide.

3. If your camera doesn?t have a ?fireworks? scene mode, put it in ?landscape? mode

Your camera automatically tries to find an object on which to focus. And when presented with a black featureless sky, the camera doesn?t know what to do. By putting your camera in ?landscape? mode, you?ll be presetting the focus to infinity and narrowing the lens opening, which keeps both near and far objects?in focus.

4. Turn off the flash
Turning your flash off will let the camera?know that it?only has available light to take a picture. This is important?because the camera will then keep the shutter open long enough to capture the fireworks. The flash button is usually a separate button on the back of the camera. On some cameras, you can?t turn off the flash unless you put it in a scene mode or program mode (P).

5. Turn down the ISO
High ISO will crank up the sensitivity of the camera so it can see details in the dark. However, the fireworks themselves are quite bright. So, to avoid overexposure and reduce film noise, take your camera out of Auto ISO and change the setting to ISO 100 or even lower. The ISO setting is usually found under the main menu. You may have to put your camera in program mode to change this setting.

Defending champion Kvitova exits Wimbledon

WIMBLEDON, England (AP) ? Petra Kvitova was nervous the first time she stepped onto Centre Court as defending champion a week ago, feeling the weight of the tradition and the expectations that come with that title.

She had overcome those nerves by the time she walked out again Tuesday to face Serena Williams in the quarterfinals, only to find a much more difficult opponent in a four-time Wimbledon winner who knows all about performing well on tennis' biggest stage.

Kvitova played one of her best matches of the tournament and still lost, overpowered 6-3, 7-5 by the hard-serving Williams, who reached her eighth Wimbledon semifinal.

"I think it was great match from both of us, and I think that she just served much better than me," Kvitova said. "I think there were some really important points that I could play better. I think that was the difference."

Kvitova has struggled following her first Grand Slam title at the All England Club last year, and has yet to reach a final in 2012. So coming in to Wimbledon as the woman to beat was a bit daunting.

"For me it was difficult (in the) first round when I went to Centre Court," Kvitova said. "That was tough for me to be strong mentally because I played badly before, so I didn't feel much better. Then I think after the first round was good, and I didn't thinking about that I'm defending champion. I just played every match ... and I was more relaxed."

It's just that Williams was simply better.

The 13-time Grand Slam winner hit 13 aces ? including three in the last game ? to end Kvitova's 11-match winning streak at Wimbledon. Her last loss here also came against the American, in the 2010 semifinals.

Williams seized control by breaking Kvitova for a 4-2 lead in the first set and then never gave her opponent a chance to get back in the match. She saved a set point when trailing 5-4 in the second with a hard serve down the middle that Kvitova returned into the net. Williams won 86 percent of the points on her first serve.

"I think that's why she's the great champion, because she knows what she needs to play in the important points," Kvitova said. "It's really tough to beat her."

Williams knows what's it like to be the player everyone is trying to beat at the All England Club. She has successfully defended the title twice ? in 2003 and 2010 ? before losing it the next year.

"It's definitely not easy. I think when I defended my first major I didn't win," Williams said. "But she did great. She held herself in ultimate class and played her heart out. I don't think I've ever seen her play so well."

Williams will next play Victoria Azarenka, who beat unseeded Tamira Paszek of Austria 6-3, 7-6 (4) despite failing twice to serve out the match.

In a match that was moved from Court 1 to the roof-covered Centre Court because of a series of rain delays, Azarenka was broken for the first time when leading 5-4 in the second set. She broke right back but then wasted a second opportunity to serve it out, before converting her second match point in the tiebreaker when Paszek sent a backhand long.

The other semifinal will feature Angelique Kerber against third-seeded Agnieszka Radwanska. Kerber beat fellow German Sabine Lisicki 6-3, 6-7 (7), 7-5 despite wasting three match points in the second set, while Radwanska reached her first Grand Slam semifinal by outlasting Maria Kirilenko 7-5, 4-6, 7-5 in a rain-affected match that saw several suspensions and was moved onto Centre Court from Court 1 for the last four games.

"I think today was for me, like, 40 hours," Radwanska said. "I was on and off all the time, waiting pretty much all day. So It wasn't easy for me, especially because of the conditions. It was raining and windy as well."

The rain caused disruptions for several of the men as well. Five fourth-round matches had been suspended in progress or postponed completely on Monday because of the persistent showers.

Jo-Wilfried Tsonga overcame an ailing back and a one-set deficit to beat American Mardy Fish 4-6, 7-6 (4), 6-4, 6-4. David Ferrer also advanced in the first match on Centre Court, where organizers again came under scrutiny for their use of the retractable roof. Their decision to open and then close it caused the start of Ferrer's match against Juan Martin del Potro to be delayed by about 40 minutes. Ferrer needed less than two hours to beat del Potro 6-3, 6-2, 6-3 and will face fourth-seeded Andy Murray.

Murray made the final eight for the fifth straight year by beating the 16th-seeded Marin Cilic 7-5, 6-2, 6-3, while Florian Mayer ousted Richard Gasquet of France 6-3, 6-1, 3-6, 6-2. American qualifier Brian Baker's remarkable run ended with a 6-1, 7-6 (4), 6-3 loss to 27th-seeded Philipp Kohlschreiber of Germany.

"We stopped, obviously, a lot," Murray said. "You're always a little bit edgy when you come out after a rain delay when you have the momentum with you. You stop, and then you come back out, and it feels a bit like you start from scratch again. I needed to serve well today and I got a lot of free points that helped me out."

The 126th-ranked Baker was trying to become the third American qualifier to reach the quarterfinals at the All England Club. He was playing in Wimbledon's main draw for the first time after being off the tour for more than five years because of a series of operations, one on his right elbow. He was ranked 458th at the start of 2012 and will next week rise inside the top 100.

"It's been an unbelievable run," Baker said. "Can't be too upset about that, even though as a competitor (I'm) definitely pretty frustrated right now. ... Hopefully I'll learn from it and have more opportunities."

In the other men's quarterfinals on Wednesday, defending champion Novak Djokovic takes on Mayer, six-time winner Roger Federer faces Mikhail Youzhny of Russia and Tsonga is up against Kohlschreiber.

Triple-digit temps back as power slowly restored

After suffering through oppressive heat and power outages neighborhoods attempted to slowly clear the debris ? but it may be the weekend before everyone has power again. NBC's Tom Costello reports.

By msnbc.com staff and NBC News

With power, and air conditioning, still out in nearly 1.3 million homes and businesses -- and many of those not likely to be reconnected for days -- triple-digit temps returned to some central U.S. cities on Tuesday. Even more areas were forecast to reach or top 100 over the next few days as the heat once again expands eastward.

Parts of Montana and Wyoming topped 100, while?St. Louis saw 100 degrees by 4 p.m. on Tuesday -- and with the humidity it felt like 104.

Kansas City, Mo., reached 99 degrees but it felt like 103. Minneapolis, Minn., only got to 95 but it, too, felt like 103.?

Dozens of other cities, many of them hit with power outages during the fierce storms last weekend, were still sweltering with yet another day in the 90s.


The National Weather Service early Tuesday?issued excessive heat warnings for parts of Minnesota, Wisconsin, Indiana, Ohio, Illinois, Missouri and Kentucky.?

That heat will expand "eastward over the next few days," it added. "Much of the eastern third of the country will see a resurgence of the heat experienced last weekend."

Kevin Lamarque / Reuters

A sign bears the bad news for members of Sleepy Hollow Bath and Racquet Club in Falls Church, Va., on Tuesday. The pool has been closed since last Friday night when a violent storm caused massive power outages in the Washington area.

The July 4th forecasts include: St. Louis at 104; Kansas City at 102; Little Rock, Ark, at 101; and Memphis, Tenn., and Minneapolis at 100 degrees.

On Monday, the power outages were reduced by about a million customers.?But residents and businesses were still struggling with outages in Indiana, Kentucky, Maryland, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, Washington, D.C., and West Virginia.?

In Washington, D.C., where blackouts are a frequent problem in the summer months, Mayor Vincent Gray urged President Barack Obama to declare a state of emergency.

"I think people are fed up with power outages, and we need a game-changer," Gray said. "We need an approach now that's going to stop this in the first place."?

In Chicago on Monday, more than 250,000 Chicago-area customers were knocked offline by Sunday's storms; that number was reduced to 48,000 by Tuesday morning, NBCChicago.com reported.

In Ohio, some 300,000 customers remained without power.

/

As nearly 1.5 million people across the country woke up Tuesday to another day with no power, the National Weather Service warned dangerously high temperatures would be persisting through the end of the week in some states.

Much of the devastation to the power grid was blamed on last weekend's rare "super derecho," a storm packing hurricane-force winds across a 700-mile stretch from the Midwest to the Atlantic Ocean.

The derecho moved quickly with little warning. The straight-line winds were just as destructive as any hurricane ? but when a tropical system strikes, officials usually have several days to get extra personnel in place.

So utility companies had to wait days for extra crews traveling from as far away as Quebec and Oklahoma. And workers found that the toppled trees and power lines often entangled broken equipment in debris that had to be removed before workers could even get started.?

The largest U.S. home and auto insurer, State Farm, said it had received about 29,000 claims from last weekend's storms, more than three-quarters of them for house damage.?

USAA and Nationwide said they had received more than 12,000 claims in total from the weekend storms. Most were for home damage.?

Officials feared the death toll, already at 23, could climb because of the heat and widespread use of generators, which emit fumes that can be dangerous in enclosed spaces.

How are you faring? Tell us on Facebook

The Weather Channel?s website, weather.com, said the worst heat on July 4 would be located over the central states, with parts of the Midwest seeing highs about 5 to 15 degrees above average.

?The sultry conditions will also extend eastward into the Mid-Atlantic, including Washington, D.C., and Philadelphia,? wrote weather.com meteorologist Chris Dolce.

Dolce warned that a cold front would bring scattered storms to the Northeast on July 4, saying ?a few of these storms could be severe with damaging winds and hail.?

?Parts of the Southeast may deal with pop-up afternoon and evening thunderstorms, particularly in the southern Appalachians and south Florida,? he added.

Cooling centers for residents who don't have air conditioning have opened up across the country. In Virginia, in response to the number of cooling shelters in the area that don't allow animals,?a gourmet pet bakery opened up a cooling center just for pets,?wamu.org reported.?

In Wheaton, Ill., a suburb of Chicago, July 4 fireworks and a parade were canceled due to damage from Sunday's thunderstorms.

"I don't think there's a block of houses that doesn't have half a dozen trees down, or parts of trees. It's a real mess to get around," resident Donald Sender told NBCChicago.com?as he refueled his generator.

Years before diagnosis, quality of life declines for Parkinson's disease patients

Years before diagnosis, quality of life declines for Parkinson's disease patients [ Back to EurekAlert! ] Public release date: 2-Jul-2012

Research published in the Journal of Parkinson's Disease

Amsterdam, NL, July 2, 2012 Growing evidence suggests that Parkinson's disease (PD) often starts with non-motor symptoms that precede diagnosis by several years. In the first study to examine patterns in the quality of life of Parkinson' disease patients prior to diagnosis, researchers have documented declines in physical and mental health, pain, and emotional health beginning several years before the onset of the disease and continuing thereafter. Their results are reported in the latest issue of Journal of Parkinson's Disease.

"We observed a decline in physical function in PD patients relative to their healthy counterparts beginning three years prior to diagnosis in men and seven and a half years prior to diagnosis in women," says lead investigator Natalia Palacios, PhD, Department of Nutrition, Harvard School of Public Health. "The decline continues at a rate that is five to seven times faster than the average yearly decline caused by normal aging in individuals without the disease."

The study included 51,350 male health professionals enrolled in the Health Professionals Follow Up Study (HPFS) and 121,701 female registered nurses enrolled in the Nurses' Health Study (NHS). In both ongoing studies, participants fill out biannual questionnaires about a variety of lifestyle characteristics and document the occurrence of major chronic disease. In the NHS study, questionnaires measured health-related quality of life in eight areas: physical functioning, role limitations due to physical problems, role limitations due to emotional problems, vitality, bodily pain, social functioning, mental health, and general health perceptions. In the HPFS, only physical functioning was assessed.

Researchers identified 454 men and 414 women with PD in the two cohorts. At 7.5 years prior to diagnosis, physical function among PD cases, in both men and women, was comparable to that in the overall cohort. A decline began approximately 3 years prior to diagnosis in men and approximately 7.5 years prior to diagnosis in women. Physical function continued to decline thereafter at a rate of 1.43 and 2.35 points per year in men and women, respectively. In comparison, the average yearly decline in individuals without PD was 0.23 in men and 0.42 in women. Other measures of quality of life, available only in women, declined in a similar pattern.

Dr. Palacios notes that a strength of the study is the availability of prospective data on both PD patients and a healthy comparison group, and the ability to chart the deterioration in functioning and quality of life over the whole study follow-up, which included many years prior to diagnosis.

"This result provides support to the notion that the pathological process leading to PD may start several years before PD diagnosis," says Dr. Palacios. "Our hope is that, with future research, biological markers of the disease process may be recognizable in this preclinical phase."
