Automatic measurement of intensity of motion activity of video segments
We present a psycho-visual and analytical framework for automatic measurement of motion activity in video sequences. We construct a test-set of video segments by carefully selecti...

Content Adaptive Wyner-ZIV Video Coding Driven by Motion Activity
In distributed video coding (DVC), the video statistics are exploited, partially or totally at the decoder. A particular case of DVC, WynerZiv video coding deals with lossy source...
