pedestrian tracking/ this post about how to use OpenCV s HOG-based pedestrian detector: How can I detect and track people using OpenCV? ... of opencv. that said it should be easy to hack the opencv source code

在vs2013平台下，利用opencv中的HOG特征加SVM分类器进行车标识别。-In the VS2013 platform, the use of opencv in the HOG feature SVM classifier for vehicle identification.

HOG特征通过计算和统计图像局部区域的梯度方向直方图来构成特征，程序可以对图片中的hog特征进行可视化梯度大小和方向。(The HOG feature is constructed by calculating and counting the gradient direction histogram of the local area of the image. The program can visualize the gradient size and direction of the h
