Notes on Wavelet Compression
Currently the best compression available for natural images.
- Excellent rate-fidelity curve.
- Encoder and decoder well matched in speed.
- No training required.
- SPIHT has good time complexity.
- Wavelet compressed image do not have the blockiness found in VQ and JPEG coded images.
- Arithmetic code doesn’t add much.
Wavelet compression is very practical
