| Abstract: | Satellite image is a kind of high entropy images. In this paper, a method of the lattice vector quantization (LVQ) for coding and compression is studied for satellite image. The property of lattice vector quantization is analyzed. Some kinds of lattice are listed. The experiment result indicates that the distortion is little by using the LVQ method for coding and compression, and the computational expense is low. This method is more suitable for coding and compression of satellite image. |
