Description: 实现一个通用的高通、低通、带通和带阻滤波器函数。其中又分别实现理想、巴特沃思和指数等滤波形式。用实现的函数对图1(lena_noise.bmp)进行低通处理,图2(lena_blur.bmp)进行高通处理,处理后分别进行伪彩色增强。-achieve a common high-pass, low-pass, band-pass and band stop filter function. It also achieve the desired respectively, Butterworth filter and index form. With the realization of a map function (lena_noise.bmp) low-pass processing, Figure 2 (lena_blur.bmp) Qualcomm, were treated for pseudo-color enhancement. Platform: |
