摘　　要：利用小波变换对MRI医学图像进行增强处理,使原图像中较模糊、对比度差的细节得到增强,其纹理清晰,处理结果优于传统的直方图均衡和Laplace锐化等图像增强方法。The medical image was enhanced by means of the wavelet transform. The result indicated that the output image had adequate contrast,obvious levels.The dim and low-contrast detail was enhanced. The method was preceded with that the histogram enhancement and the Laplace enhancement.

关 键 词：小波变换 医学图像 图像增强
