Is it possible you didn't train enough? How many classes, and what did you use for max batches?
See this example which shows possibly similar results when the network hasn't been fully trained: https://www.ccoderun.ca/programming/2020-01-04_neural_network_training/#Details

Iam using the original yolov4 weights / cfg (coco dataset). Resolution is set to 320x320.
I think Car/Truck/Bus looks too similarly.
Detection output for a single frame, coordinates are identical:
[('car', '38.09', (1303.8668212890625, 623.4581909179688, 430.96990966796875, 265.2787170410156)), ('truck', '31.08', (1303.8668212890625, 623.4581909179688, 430.96990966796875, 265.2787170410156)), ('bus', '22.33', (1303.21435546875, 621.9441528320312, 430.59820556640625, 273.7593078613281))]
vehicle detection is kinda tricky because of the similarities and different angles. one think id try is to dewarp the fisheye on your camerastream to provide more accurate input for the cocoset. higher threshold, tinker with iou and nms and use a higher resolution for better accuracy
Hi i want to measure the size of different vehicles. But in some cases i got two classes (Bus,Car) (Truck,Car) for the same object. Is there any Filter/ Idea to elimtate the double detection on the same object. In my understanding NMS works only for the same class.
I could filter the deteciton list for the highest confidence and eliminate other detections, but i dont like a hack like this.
using yoloV4 and sort.py for tracking
Best Regards Martin
