摘要

红外成像已成为最重要的图像源之一，目前在许多不同的应用中得到了应用。因此，红外图像的压缩对于红外图像的传输和存储是非常重要的。将小波域的子带编码应用于红外图像是一种减少图像冗余的好方法。本文将SCWD应用于一级和二级分解的红外图像，并与标准图像进行了比较。将SCWD应用于红外图像，比特率为1.25 bpp，具有非常高的PSNR和出色的感知质量。同时，获得了0.312 bpp的比特率，具有较高的PSNR和很好的图像感知质量。

Infrared image compression using subband coding in the wavelet domain

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.
