  1. Usually, we consider a sampling technique in which each sample is obtained by averaging a diamond portion of the picture, as we know, a large amount of information of a image in nature mainly gathered the small area, at the same time <, . but to finger print gray image, a fine degree of quantization is particularly important for samples taken in regions of a picture across which the gray level changes slowly

    目前國內外圖像濾波常用的方法有線性濾波和非線性濾波。線性濾波有完善的理論基礎,數學處理也簡單,易於fft實現,在濾波技術中佔有及其重要的地位,但對于像素受污染的指紋圖像而言由於脈沖噪聲的重脫尾,處理效果並不太理想。
