Based On Wavelet Transform Infrared Image Compression Technology

Still image and digital video data rates are very large. Data rates of this magnitude would consume a lot of the bandwidth ,storage and computing resources in the typical personal computer. For this reason ,image and video compression standards have been developed to eliminate picture redundancy ,allowing information to be transmitted and stored in a compact and efficient manner.Wavelet transform is a new type of mathematic tools. In time-frequency property,wavelet transform is better than Fourier Transform. Recently many researches such as signal and image processing ,computer visualization and speech recognition/synthesis use wavelet transform ,especially in image coding research. This article first talk about some theories of wavelet,then give some rules about the wavelet selection . Finally it show the fact that wavelet transform perform good result in infrared image.
