Image Coding Using the Self-Organizing Map of Multiple Shell Hypercube Struture
다중쉘 하이퍼큐브 구조를 갖는 코드북을 이용한 벡터 양자화 기법
Abstract
When vector quantization is used in low rate image coding (e.g., R<0.5), the primary problem is the tremendous computational complexity which is required to search the whole codebook to find the closest codevector to an input vector. Since the number of code vectors in a vector quantizer is given by an exponential function of the dimension. i.e., L=2
