Description: 图象增强
小波变换将一幅图象分解为大小、位置和方向都不同的分量。在做逆变换之前可以改变小波变换域中某些系数的大小,这样就能够洋选择的放大所感兴趣的分量而减小不需要的分量。
给定一个图象信号,用二维小波分析对图象进行增强处理。-Image enhancement will be a wavelet transform image decomposition for size, location and direction of the weight is different. To do before the inverse transform of wavelet transform domain can change the size of certain coefficients, so that foreigners will be able to choose to enlarge the amount of interest and reduce the unwanted weight. Given an image signal, using two-dimensional wavelet analysis of images to enhance treatment. Platform: |
