本文结合小波多级变换后不同方向、不同尺度的系数相关性，提出了一种多分辨率的分类矢量量化方案，对由不同分辨率水平、不同方向的小波系数组成的矢量块进行分类量化编码，并设计了相应的性能良好的分类器，给出了不同条件下的实验结果和数据，从而证明了该编码方案不但提高了图像的质量，同时计算复杂度也有一定的降低． In this paper, we propose a multi-resolution classification vector quantization scheme based on the correlation of coefficients in different directions and different scales after wavelet multistage transform, classify and quantize the vector blocks composed of wavelet coefficients of different resolution levels and directions , And design the corresponding classifier with good performance. The experimental results and data under different conditions are given, which proves that the coding scheme not only improves the image quality but also reduces the computational complexity.
