| 摘 要： | 以Haar小波为例，对光学小波变换过程进行数值模拟．模拟程序包含原图像的读取、Haar小波的构造、频谱变换、空间匹配滤波等内容，能够模拟Haar小波对图像边缘增强过程．通过改变Haar小波的宽度，分析了不同尺度小波的光学变换结果．同时，还提出了Haar小波的二次滤波方法，图像的边缘得到进一步增强．

| Abstract: | Numerical simulations of optical wavelet transform are developed based on Haar wavelet analysis. The simulation program involves input of original images, construction of Haar wavelet, spectrum transform and space-matched filtering. It can simulate the procedure of the edge enhancement of image by Haar wavelet transform. The results are analyzed with different scales of optical wavelet transforms by changing the widths of Haar wavelets. Furthermore, a double filtering method is proposed, which makes the result further enhanced. |
