Abstract

This paper presents new algorithm based on discrete cosine transform and LBG algorithm using vector quantization for image compression of color images. Vector quantization is mainly divided into three parts i. e Encoding process, Codebook design, Decoding process. In vector quantization generation of codebook is important so that the distortion between the original image and the reconstructed image is minimum. In this RGB component of color image are converted to YCbCr before DCT transform is applied. Y is luminance component; Cb and Cr are chrominance components of the image. This paper compares three different algorithms for vector quantization of color images. It is observed that the performance of new algorithm LBG using DCT is better than LBG. Performance is measured using PSNR and MSE.
