Hello,

I managed to run deepstream\_app\_config\_yoloV3.txt successfully. Now I want to change the app according to my personal requirement. Imagine I want to print “Person detected” in the terminal when the yolo detector identify a person in a frame.

I went through the files in objectDetector\_Yolo folder, but I wasn’t able to find the relevant file which I can use to do my task. Can you please give me a little guidance ?

After going through the code I found the solution.

nvdsparsebbox\_Yolo.cpp file contains the details of the detected objects. maxIndex variable carries the object label index which is related with labels.txt file.
