基于方差分类初始化码书的三维邻域SOM算法
THE 3D NEIGHBORHOOD SOM ALGORITHOM BASED ON CODEBOOK INITIALIZATION WITH VARIANCE CLASSIFICATION
摘要
Abstract
Codebook design is a key problem in vector quantitation （VQ） algorithm. In order to overcome disadvantages of existing Self-Organizing feature Maps （SOM） algorithm and to improve performance of vector quantitation codebook, 3D neighborhood SOM algorithm based on codebook initialization with variance classification is proposed in. A variance classification method is proposed to improve codebook initialization, taking into consideration effect of initial codebook on codebook quality. Experimental data confirm that the proposed algorithm is better for designing vector quantization codebook..关键词
