无符号大数类 实现了大数四则运算 比较 求余数 其中大数乘法采用分治 除法采用模拟竖式-No sign of large numbers class implements the large numbers seeking four more than the number of operations in which the multiplication of large numbers using analog vertical divider partition

对原始图像在水平方向和垂直方向与2个滤波器(低通、高通)相卷积，可以得到4块面积为原图像1/4的子图，分别为水平方向低频和垂直方向低频(HH)、水平方向低频和垂直方向高频(HG)、水平方向高频和垂直方向低频(GH)、水平方向高频和垂直方向高频(GG)。-The original image in the horizontal direction and vertical direction and two filters (low pass, high pass) with convolutio

This paper presents a text line segmentation method for printed or handwritten historical Arabic documents. Documents are first classified into 2 classes using a K-means scheme. These classes correspond to document complexity (easy or not eas
