Detection Issue in yolov3

[Akshay3895]

@AlexeyAB I am using pjreddie/darknet for object detection and had some issues in detection results. This is a snapshot of it:

If you see the image it has detected the Chair as person D and detected two boxes for Person C.

Would like to know what is causing this problem and is there any solution to it ? And is there any way to remove the multiple detections for the same object ?

NOTE: This only happens in about two frames max, otherwise it detects everything perfectly.

Thanks. Need Help!

@Akshay3895 Hi,

• What is the different between Person C and D?
• Increase width=608 height=608 or 832x832 in cfg-file and detect again.
• Improve your training process: https://github.com/AlexeyAB/darknet#how-to-improve-object-detection

If it doesn't help, then increase nms to 0.6:
