Human Body Detection in opencv

Previously, we used MATLAB to implement algorithms. Recently, we started to use opencv as a target tracking algorithm. We found that opencv is really powerful. It integrates many algorithms and encapsulates many functions, the method is similar to MATLAB, but it is more efficient than Matlab. The following describes the human body detection code using the hog algorithm, which is similar to peopledetect. cpp in opencv. However, I modified some code to detect continuous video sequences.

The Code is as follows:

#include <fstream>#include <string>#include <cv.h>#include 
Hog. setsvmdetector (hogdescriptor: getdefaultpeopledetector (); obtains the SVM detection operator.
Hog. detectmultiscale (IMG, found, 0, size (8, 8), size (32, 32), 1.05, 2); the detection result is obtained.
