ImageFilterinFrequencySpace

代码说明：

  目的是改善影像质量，包括去除高频噪声与干扰，及影像边缘增强、线性增强以及去模糊等。分为低通滤波（平滑化）、高通滤波（锐化）和带通滤波。(The purpose is to improve the image quality, including the removal of high frequency noise and interference, and image edge enhancement, linear enhancement and deblurring. Into a low-pass filter (smoothing), high-pass filtering (sharpening) and bandpass filtering.)
