Abstract

Based on the logarithmic and exponential transform, an efficient Log-Exp still image compression system is proposed. The Log-Exp compression is designed for the high quality still image, especially for the PSNR above 36. At the similar image quality (Log-Exp PSNR = 41.52 and JPEG PSNR = 41.23), the Log-Exp compression can get the higher compression ratio than JPEG by 1.84 times for the benchmark image lena. Besides, the Log-Exp compression is computing in pixel-by-pixel without the block artifacts. In comparison with the JPEG compression result (bpp = 0.99, PSNR = 26.9), the Log-Exp compression uses less bpp (bpp = 0.87) to get higher image quality (PSNR = 36.38) for the benchmark image baboon.
