A joint source channel coding scheme for error resilient image transmission is proposed. A practical image coder was introduced in [1] using modified Differential Pulse Coded Modu...

Compound images contain a mixture of natural images, text, and graphics. They need special care in the use of compression because text and graphics cannot withstand the significan...
A fully automated architecture for object-based region of interest (ROI) detection is proposed. ROI's are defined as regions containing user defined objects of interest, and ...
Region-based functionality offered by the MPEG-4 video compression standard is also appealing for still images, for example to permit object-based queries of a still-image database...
In this work we introduce and analyze algorithms for fractal image compression on massively parallel SIMD arrays. The di erent algorithms discussed di er signi cantly in terms of ...
