文中提出了一种基于小波变换的格型矢量量化 (L VQ)混合编码方法 ,在图像编码过程中充分利用了图像小波系数的分布特征和人类视觉系统 (HVS)的特性 ,对于不同频域的信息采用不同的编码方法。实验结果也表明 ,此算法实现简单 ,可以达到很好的压缩效果 In this paper, we propose a hybrid vector quantization (LVM) hybrid coding method based on wavelet transform, which makes full use of the distribution characteristics of image wavelet coefficients and the characteristics of human visual system (HVS) in the process of image coding. For different frequency bands Information using a different encoding method. Experimental results also show that this algorithm is easy to achieve, and can achieve good compression effect
