Data compression method and system using globally optimal scalar quantization |
摘要 |
A signal encoding/decoding system and method are provided, where a signal quantizer is designed by minimizing a target function in accordance with a rate/distortion tradeoff. The system and method can be applied to give lossy compression of data for graphic or music files and also to smart-server applications, in accordance with the available bandwidth.
