Kernel-Entropy-Component-Analysis
这篇文章是一种特征降维的方法,不过跟一般的计较离散度的方法不同,这个特征变换的准则是:尽可能地保留原始样本的熵(Kernel Entropy Component Analysis

PSO
说明: 实现
%1、利用RGB模型识别天空区域;2、利用边缘识别检测天空边缘分割线;3、利用预测边缘点和实际边缘点的周围区域的均值滤波与本边缘点下方的像素之间的差异大小来修正天空边缘分割线
%4、将sky_seg+depthmap_v2中多余的带注释的地方删掉了
%!!!记得在295行,一定要改动是用I6还是I7,如果用sky_initia(f = edge(double(BW),'canny',thresh,sigma);)

Hough_Process
可实现答题卡阅卷系统中的图像倾斜矫正,采用Hough进行直线检测,并根据所定位的特征直线位置计算倾斜角度,再进行图像旋转,得到校正结果(chieve answer sheet scoring system image tilt correction, performed using Hough line detection, and calculates the inclination angle in accordance with the target characteristic linear position, then rotate the image, corrected results)
