Paper Abstract

This paper presents a multispectral image compression method based on vector quantization technique that uses fuzzy c-means (FCM) algorithm to generate the codebook. There are two ways to form the vector set from the input image: the intraband vector forming where each vector was formed by dividing the input image into blocks, and the interband vector forming where each vector was formed by the gray values of all bands representing a pixel. In this research, a modified version of FCM was used to reduce the computational time. The experimental results comparing the effect of both vector forming methods are given.
