In this paper, we propose a novel efficient scheme for robust video transmission over wireless channels. The schema consists of motion compensated spatio-temporal wavelet decompos...
In this study, we suggest a method to adapt an image retrieval system into a configurable one. Basically, original feature space of a content-based retrieval system is nonlinearly...
This paper presents a technique for lossy compression of dense range images. Two separate compression schemes are applied. The first scheme (geometric compression) reduces redunda...
