We propose a quad-tree scheme for obtaining sub-pixel estimates of interframe motion in the frequency domain. Our scheme is based on phase correlation and uses motion compensated ...

Global motion is estimated either in the pixel domain or in block based domain. Until now, all the approaches regarding the latter are based on fixed sized blocks while the recent...

When estimating the dense motion field of a video sequence, if little is known or assumed about the content, a limited constraint approach such as optical flow must be used. Since...
