The Application of Wavelet Transform to Breast Near-Infrared Images

Near-infrared imaging is a method of lossless imaging, but the images got by this method have bad contrast and obscure edge, these make diagnosis difficult to make. In this article, after briefly introducing the basic theory, aiming at the multi-resolution of wavelet, a new method of image enhancement has been presented. After preliminary denoising, the noise is restrained by this method of image enhancement. Finally, another transformed image with other method is simply fused with the image we have just got. The results show that images finally got have higher diagnostic value
