A new approach of reliable image and video transmission over noisy channel is proposed. The proposed subband modulation scheme combines source coding and channel modulation scheme...
In this paper we present a framework combining differential geometry and scale-space to show that local geometric invariants of image contours such as tangent, curvature and deriv...
A method is introduced that detects human faces in color images by rst separating skin regions from nonskin regions and then locating faces within skin regions. A chroma chart is ...
: An explicit formula is presented for reconstructing a This article derives an explicit formula for the integer values finite-support object defined on a lattice of points and tak...
We propose and consider a secure printing system for the distributed printing of documents and images over the World Wide Web. This system enables secure sharing, commerce, and co...

To convert a compressed video sequence to a lowerresolution compressed video, one typically needs to decompress the original sequence, down-sample each frame, and recompress it. I...

This paper presents a comprehensive distortion metric for digital color images. It is based on a normalization model of the human visual system that incorporates color perception....
This paper introduces a new generalisation of the familiar scale-space and wavelet representations, designed specifically to deal with the complexities of representing motions ind...
