| dc.description.abstract | In this paper, a predictive locally adaptive vector quantization (PLAVQ) for real-time image compression is developed and simulated. It is a hybrid of improved predictor, LAVQ and (VLC). The latter is a combination of Laplacian quantizer, Huffman coding, and optimum-modified B1-code for encoding the codewords and indices, respectively. Simulation shows that an improvement in speed of about 76% can be achieved with about 1.1 dB increase in the peak signal-to-noise ratio (PSNR) at the same bit rate. Optimization of the modified B1-code decreases the bit rate with an average of 37% for the same image quality. Simulation data of PSNR and bit rate vs. error threshold can be expressed by a decaying exponential model independent of image type. | |
