This has created the folder
Next to the pictures to get images stored in the folder
Mat faceROI=frame_gray (faces [0]). The region of interest//ROI
Mat myFace.//set up an own face store
The resize (faceROI, myFace, Size (92, 112));//store is 92 * 112 photos please ensure good posture, because the picture too much cause error

}


This folder is set according to your input
That is to say, you enter one after his own name to create a folder with the program of photos will be stored in this folder, can realize the function of this line
Thank you I bosses to help.

CodePudding user response:

Sprintf (filename, surprised "% s % jeter pg," dir, + + count);
The output filename to see if effective path name, file name and directory separator,
