Abstract :
This paper proposed an improved JPEG compression algorithm based on Haralick sloped-facet model. Different areas after segmentation were taken into account in this algorithm and different areas are compressed in different proportion. The experiment results show that the quality of reconstructed images is better than the traditional JPEG compression algorithm at the same bit rate about 0.3 dB.
