Convert video sequence to Image Sequence

In video processing, you often need to convert the video sequence. On the one hand, it is for convenience of processing, and on the other hand it is also a requirement of the project. If you want to convert a video sequence to an image frame, you can perform necessary pre-processing for the image sequence, such as tagging and extracting prior information. Here we use a simple video in the opencv platform library to convert an input video sequence to an image sequence program.

int _tmain(int argc, _TCHAR* argv[]){const string strFilePath="D:\\testVideo\\person.avi"; VideoCapture cap;Mat frame;int frmNum = 0;char _path[255];char prefix[]="D:\\images\\";char postfix[]=".jpg";cap.open(strFilePath);if( !cap.isOpened() ){    printf("can not open camera or video file\n");    return -1;}for (;;){   frmNum++;   cap>>frame;  if (frame.empty())  {     printf("Video File Finished !\n");    return -1;  }  memset(_path,'\0',sizeof(char)*255);  sprintf(_path,"%sframe_%04d%s",prefix,frmNum,postfix);  imwrite(_path,frame);  imshow("video",frame);  waitKey(10); }  printf("Video File Finished !\n");  system("pause"); return 0;}
