Disparity dependent segmentation based stereo image coding
In this paper, we propose a novel rate-distortion (R-D) optimized disparity based coding scheme for stereo images. This new scheme efficiently integrates the coding of the dispari...

Efficient coding of computer generated compound images
A new compound image compression algorithm is proposed, based on Shape Primitive Extraction and Coding (SPEC). The SPEC first segments a compound image into text/graphics pixels an...

An Algorithm for Low Memory Wavelet Image Compression
As wavelet-based image coding is set to become more widely used (e.g. with the completion of the JPEG2000 standard), memory efficiency for wavelet-based coding is becoming an incr...

Image Coding using 2-D Anisotropic Dual-Tree Discrete Wavelet Transform
We propose an image coding scheme using 2-D anisotropic dual-tree discrete wavelet transform (DDWT). First, we extend 2-D DDWT to anisotropic decomposition, and obtain more direct...
