A New Initial Codebook Algorithm of Learning Vector Quantization

In vector quantization(VQ),the initial codebook design is very important for VQ codebook performances.To overcome disadvantages of existing initial codebook algorithms,a new separating mean algorithm for learning vector quantization(LVQ)based upon self-organizing feature maps(SOM) was proposed.Experimental results for image VQ show that new initial codebook algorithm is better than random and splitting algorithm.
