Description: 该程序实现了Bresenham算法画直线，将四个象限的问题通过交换端点的方法合并成一，四象限的问题。再利用sign变量，统一成一个问题。又考虑到斜率<=1，>1，不存在，最终问题分成了三种情况。-The program implements Bresenham algorithm for drawing a straight line, the four quadrants of the problem through the exchange of endpoint methods combined into one, four-quadrant problems. Re-use of sign variables, unified into a problem. Also taking into account the slope of the " = 1," 1, does not exist, ultimately, the issue was divided into three cases.

Description: kstest_2s_2d.m：功能做两样本的二维Kolmogorov - Smirnov检验
它类似于MATLAB的内置函数的“kstest2“从统计工具箱除了“kstest_2s_2d“与二维数据处理。
[小时，pValue，KSstatistic] = kstest_2s_2d（为x1，x2，α，尾）
函数在两栏输入“ד，并以“ד，其中每一列代表一个维度。其他的选项和产出是相同的含义，是“kstest2“格式。
摘要算法（峰值，1983年）：考虑四个象限（十<的X，Y<Ÿ ），（十<X,y>年），（十>的X，Y<Y)和(x>的X，Y>Ÿ ）反过来，采取了两者之间的经验累积分布的四个最后堪萨斯州最大的统计学差异。

It s similar to the MATLAB built-in funtion "kstest2" from Statistics Toolbox except that "kstest_2s_2d" deals with two-dimensional data.
[H, pValue, KSstatistic] = kstest_2s_2d(x1, x2, alpha, tail)
The function takes in 2-column inputs "x1" and "x2", where each column represents one dimension. The other options and the outputs are of the same meaning and format as "kstest2".
Algorithm summary (Peak, 1983): consider the four quadrants (x<X,y<Y), (x<X,y>Y), (x>X,y<Y) and (x>X,y>Y) in turn, and adopt the largest of the four differences between the two empirical cumulative distributions as the final KS statistic.

Description: Skew detection and correction is very important task before pre-processing of an image and it is a major problem in scanned documents, if it
not detected correctly it will lead wrong result in future during image analysis. During the scanning of the document, skew is being often introduced in the
document image. To measure the processed time and speed taken by skew detection algorithm, the Fast Fourier Transform (FFT) technique is applied
as it is fast approach for finding the angle of skewed document. This technique is used by firstly applying DCT compression and thresholding on image
to reduce timing computation and after that Fourier spectrum is obtained. Further this spectrum is divided into four quadrants and detected skewed angle
of each quadrant is measured. And finally Input image is rotated by using bilinear interpolation method.
