| Abstract: | Point to problem that the image data's increase with the increase of resolving power, in order to store and transmit the remote image data efficiently, a kind of image compression method is presented in this paper, and the effection of the threshold to the image compression ratio and energy-keeping was studied at the same time. The experiment result proved that the wavelet transform is a kind of high compression and energy-keeping ratio, fast compression speed data compression method. |
