An Image Retrieval Method Using Modified LBG Algorithm

In this paper, the investigation on using the proposed modified LBG algorithm for the image retrieval system is presented. The proposed algorithm transforms an image into multi-layer bitstream, the base layer and enhancement layer bitstream. Then the multi-layer bitstream is coded with modified LBG algorithm using partial search partial distortion for coding the wavelet coefficients to speed up the codebook generation. The experimental results show that the proposed algorithm outperforms JPEG algorithm, in compression efficiency. On the other hand, the base layer and enhancement layer bitstream, it provides superior benefits to the retrieval system compared to other compression methods. Moreover, the enhancement layer bitstream also allows fast transmission that enhances the performance of retrieval systems.
