- Opencv HOG (Histogram of Orientation Gradient) training based on Dalal method. When you try to use Opencv HOG, you may not know how the training of the SVM model is done. Here is the example Linux with Opencv2.1

- 本代码基于opencv2.2,使用时先将库文件加入输入链接。边缘方向直方图，在图像处理中经常会进行梯度操作得到方向角，此代码实现用直方图将方向角表示出来的功能。-The code is based on opencv2.2, use the first library file into the input link. Edge direction histogram, the image processing operations often get the direction of the
HOG_OpenCV
- HOG即histogram of oriented gradient, 是用于目标检测的特征描述子，该技术将图像局部出现的方向梯度次数进行计数，该方法和边缘方向直方图、scale-invariant feature transform类似，不同的是hog的计算基于一致空间的密度矩阵来提高准确率。Navneet Dalal and Bill Triggs首先在05年的CVPR中提出HOG，用于静态图像or视频的行人检测。-HOG i.e. histogram of oriented gradien

- 基于邻域灰度梯度的改进二维OTSU算法：在二维OTSU的方法上进行改进，将纵坐标改用像素点的灰度值与其邻域的平均灰度值的差的绝对值，分割图像。-Neighborhood-based two-dimensional gray-scale gradient improved OTSU algorithm: to improve on the two-dimensional OTSU method, the vertical axis instead of the absolute value of

- Canny边缘检测算法是1986年有John F. Canny开发出来一种基于图像梯度计算的边缘 检测算法，同时Canny本人对计算图像边缘提取学科的发展也是做出了很多的贡献。尽 管至今已经许多年过去，但是该算法仍然是图像边缘检测方法经典算法之一。-Canny edge detection algorithm in 1986 John F. Canny edge detection algorithm developed by the image gradient calcu
