MIT Research Amplifies Invisible Detail In Video

An anonymous reader writes "MIT researchers have invented an algorithm which is able to amplify motion in video that is invisible to the naked eye — such as the motion of blood pulsing through a person's face, or the breathing of an infant. The algorithm — which was invented almost by accident — could find applications in safety, medicine, surveillance, and other areas. 'The system is somewhat akin to the equalizer in a stereo sound system, which boosts some frequencies and cuts others, except that the pertinent frequency is the frequency of color changes in a sequence of video frames, not the frequency of an audio signal. The prototype of the software allows the user to specify the frequency range of interest and the degree of amplification. The software works in real time and displays both the original video and the altered version of the video, with changes magnified.'"
