Describe: 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.
