Thinning-Image

基本解釋

Then dividing background block and foreground block and binarying image.The purpose of thinning image is to reduce a lot of inessential information and to get very integrated minutiae information.
然後，分割背景和前景塊，二值化、細(xì)化竝去除噪聲，消去大量的指紋冗於信息，得到較完整的細(xì)節(jié)特征信息。
The ridges in the thinned image were traced to eliminate the false minutiae connected by ridges.
