Computer scientists have isolated the movements of Olympic swimmers and diverse through a fashionable technique that reveals their motions on top of and below the water’s surface.
The work, conducted by Manhattan Mocap, LLC, beside ny University’s Movement Laboratory and also the ny Times, analyzes Dana Vollmer, WHO won 3 gold medals at the 2012 Summer Olympic Games in London, still as Abby Johnston, WHO won a medal in synchronous diving, and saint McCrory, a bronze medalist in synchronous diving.

Their work could also be viewed here.
Of explicit note is that the team’s creation of a system, AquaCap (TM), that captures underwater motion. it had been wont to show Vollmer’s butterfly and underwater swimming kick, breaking down the technique the swimmer wont to win the prize within the 100-meter butterfly in world-record time. Through a comparison of motions, the video illustrates however closely Vollmer’s kick resembles that of a dolphin swimming through the water.
Subsequent work analyzed Johnston and McCrory, showing through antecedently unseen angles their summersaults from 3- and 10-meter diving boards and marking another technical breakthrough in motion capture.
Motion capture records movements of people, WHO wear suits that replicate lightweight to alter the recording of their actions. It then interprets these movements into digital models for 3D animation typically employed in video games and flicks, like “Avatar” and “Iron Man.” Bregler and his team used a additional refined computer-vision technology, that permits for the following and recording of those movements straight from video and while not the employment of motion capture suits.
Manhattan Mocap LLC could be a new spinoff of the NYU Movement research laboratory, a pacesetter in motion capture in sports, diversion, and research project. Previous comes embrace AN examination of baseball pitcher Mariano Rivera’s delivery and gesture analysis of latest dynasty Philharmonic conductor Alan Gilbert. it’s conjointly developed a technique to spot and compare the visual communication of various speakers—also referred to as “body signatures.” Titled “GreenDot,” the project employs motion capture, pattern recognition, and “Intrinsic Biometrics” techniques. In 2008, the NYU Movement Lab’s results showed that role player Tina Fey, WHO was wide praised for imitating Republican executive pol married woman Palin’s voice and look, conjointly effectively channeled the previous AK governor’s visual communication.
