Abstract

Abstract: Controlling the quality of the images in JPEG is done by quantization tables. There are two quantization tables – one for the luminance information and one for the chrominance information. These tables have been designed for images with few sharp changes; however, typically most GPS image maps have many sharp changes; therefore, the images are not optimally compressed. In this paper we suggest to revise the standard quantization tables, so they will be more suitable for GPS image map compression.
