How you get the visulization photo like the first one ？

eagle-chase commented 1 year ago

The default algorithm used should be 3diou_ NMS, I think other NMS methods can be used for large targets or the IoU threshold can be lowered

Because their IoU is less than 0.25.

@Abyssaledge I think it need a nms between multi-class. The white is the truck and the pink is the bus. Their IOU is very large.
