Abstract :
Infrared (IR) imaging has become one of the most important image sources and is used now in many different applications. Thus, the compression of IR images is very important for the transmission and storage purposes. The application of the subband coding in the wavelet domain (SCWD) to IR images is shown to be a good tool to reduce the image redundancy. In this paper, the SCWD is applied to IR images with one and two levels of decomposition and the results are compared with a standard image. The application of the SCWD to IR images gives a bit rate of 1.25 bpp with very high PSNR and excellent perceptual quality. Also, a bit rate of 0.312 bpp is obtained with high PSNR and very good perceptual quality of the reconstructed image
