In authentication using watermarking, the original media needs to be slightly modified in order to embed a short media digest in the media itself. Lossless authentication watermar...
In this paper, we propose a methodology for embedding watermark image data into color images. At the transmitter, the signature image is encoded by a multiple description encoder. ...
Content based shape image retrieval is an important problem which gained the attention of the community. The challenge is to map the shape into compact and robust descriptor. This...
We introduce a technique for deiiecting moving objects from an image sequence obtained with a moving camera using the planarity constraint. To increase the robustness of this tech...
Robust motion estimation is obtained by integrating optical flow and region tracking methods into a closedloop architecture. To ensure robust tracking over long intervals in video...
