Abstract

In this paper, adaptive quantization algorithm with pseudo Huffman coding scheme used for image compression application integrated along with a digital pixel sensor (DPS) array is proposed. The proposed pseudo Huffman coding scheme compresses the quantization results without any loss, while saving as high as half of the bits in transmitting while comparing with the number of bits required by system without such coding scheme. Simulation results show that the adaptive quantization can usually increase the PSNR results by even higher than 25%.
