Image Segmentation Via Iterative Geodesic Averaging
We present a simple and fast method for performing unsupervised segmentation. Our method works by centering a square window on each pixel of the input image. Each pixel is then as...

Global motion estimation using variable block sizes and its application to object segmentation
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...
