| 摘 要： | 提出一种有效的图像压缩方法，利用小波变换对图像进行多分辨率分解，对小波系数进行矢量量化(VQ)编码。使用遗传算法(GA)与模糊c均值聚类(FCM)算法相结合的方法来设计码书，有效地克服了FCM算法容易陷入局部最优且对初始值敏感的缺点。实验结果表明，该算法可较大提高图像重构质量。

| Abstract: | An effective image compress method is put forward in this paper.Using wavelet transformation to decompose im-ages,wavelet coefficients are vector quantized.Codebook of vector quantization is designed through fuzzy c-mean clustering and genetic algorithm.This algorithm overcomes the shortcomings of FCM effectively.Experimental results indicate that this algorithm improves the quality of reconstructed image. |
