Brushlets: A Tool for Directional Image Analysis and Image Compression
François G. Meyer, Ronald R. Coifman · Applied and Computational Harmonic Analysis · 1997
We construct a new adaptive basis of functions which is reasonably well localized with only one peak in frequency. We develop a compression algorithm that exploits this basis to obtain the most economical representation of the image in terms of textured patterns with different orientations, frequencies, sizes, and positions. The technique directly works in the Fourier domain and has potential applications for compression of highly textured images, texture analysis, etc.
