PROJECTS :
Hybrid Neural Net and Wavelet Image compression algorithm.

Lossy audio compression algorithm based on a 1-d zerotree method.

Lossless online data compression theory based on live prediction by partial matching and arithmetic coding.

Performance-oriented and image compression-oriented variations on edge-directed interpolation theory. Enables low resolution images to be scaled to high resolution w/o significant loss of quality.
