In this paper, we present a novel framework for analyzing video using self-similarity. Video scenes are located by analyzing inter-frame similarity matrices. The approach is flexi...
In this paper we propose a new watermarking technique where the watermark is embedded according to two keys. The first key is used to embed a code bit in a block of pixels. The se...
In this paper, we present a new 3D camera motion estimationtechniqueusingopticalflow froma pairof imagestaken under a perspective projection. The problem formulation leads to the ...
The proliferation of video content on the web makes similarity detection an indispensable tool in web data management, searching, and navigation. We have previously proposed a com...
Optimal mode selection for video coding is important in minimizing visual distortion given a rate constraint, and it has been studied in the literature using a single previous mac...
An efficient compression scheme for color-quantized images based on progressive coding of color informationhas been developed. Rather than sorting color indexes into a linear list...
A common problem in most active contour methods is that the recursive searching scheme can only return a local optimal solution. Furthermore, the internal energy of the snake is n...
Images and videos can be indexed by multiple features at different levels, such as color, texture, motion, and text annotation. Organizing this information into a system so that u...
