Fast Code Enhancement with Local Search for Fractal Image Compression
Optimal fractal coding consists of finding in a finite set of contractive affine mappings one whose unique fixed point is closest to the original image. Optimal fractal coding is ...

Wavelet-Based Coding of Three-Dimensional Oceanographic Images Around Land Masses
We describe an algorithm for the embedded coding of 3D oceanographic images. These images differ from those arising in other applications in that valid data exists only at grid po...
