Multichannel SVD-based image de-noising
: - In this paper, we propose a multichannel SVD-based image de-noising algorithm. The IntDCT is employed to decorrelate the image into sixteen subbands. The SVD is then applied to...

A new rate-minimizing matching criterion and a fast algorithm for block motion estimation
We present a new block matching criterion for motion estimation in video coding that will give better encoded video quality than the commonly used sum of absolute differences (SAD...

Automatically linking multimedia meeting documents by image matching
We describe a way to make a hypermedia meeting record from multimedia meeting documents by automatically generating links through image matching. In particular, we look at video r...

Robust digital image-in-image watermarking algorithm using the fast Hadamard transform
In this paper, a robust and efficient digital image watermarking algorithm using the fast Hadamard transform (FHT) is proposed for the copyright protection of digital images. This...
