Gvqprog.zip
An old source code. It contains C source code for training vector quantization (VQ) codebook. Three algorithms, GVQ [1], LBG [2] and LVQ [3] have been implemented

VQcoding.zip
由matlab编写,带GUI界面。对bmp文件进行Vector Quantization。运行其中的VQ_GUI.m文件。
程序肯定是调试无误的。虽然比较耗时,但是最后能达到较好的图像效果和SNR。毕竟相比于VC,matlab运行较慢。
注意在点open打开了一个bmp文件过后,一定要先点VQ code,进行其他操作才能有效。
