说明：  利用小波变换实现图像增强的算法。针对含有微弱纹状物或点状物的图像，对这些微弱纹状物进行自适应放大，加大其对比度，从而达到增强的目的。
(Using wavelet transform to achieve image enhancement algorithms. Contains patterns for weak point-like or flakes of the images of these faint stria-like adaptive amplification, an increase in the contrast, so as to achieve the purpose of enhancement.)
