Hardware Testing For Error Tolerant Multimedia Compression based on Linear Transforms
In this paper, we propose a system-level error tolerance scheme for systems where a linear transform is combined with quantization. These are key components in multimedia compress...

A scalable and programmable architecture for 2-D DWT decoding
The compression of still images by means of the discrete wavelet transform (DWT), adopted in the JPEG-2000 and MPEG-4 standards, is becoming more and more widespread because it yie...

An automatic scheme for stereoscopic video object-based watermarking using qualified significant wavelet trees
In this paper a fully automatic system for embedding visually recognizable watermark patterns to video objects is proposed. The architecture consists of 3 main modules. During the...
