ABSTRACT:
A method acquires a plurality of input videos. The frames of each input video are acquired at a fixed sampling rate. Joint analysis is applied concurrently and in parallel to the input videos to determine a variable and non-uniform temporal sampling rate for each input video so that a combined distortion is minimized and a combined frame rate constraint is satisfied. Each input video is then sampled at the associated variable and non-uniform temporal sampling rate to produce output videos having variable temporal resolutions.
