I am viewing the below density dotted image. How can we interpret which heatmapped dot are likely to be counted.
Currently I do simply output.sum() ,is there any way i can do sum based on some threshold value which indicates high likelyhood of an object count ?
Actually, you could not find the accurate localization of the counted objects, since this method is density-based. If you wanna count objects by accurately localizing objects, you should seek to some point-based methods.
@zhiyuanyou do you have any pointers,
but density labels that were chose for the models training were point based only
If you wanna find the accurate localization of the counted objects, I recommend CrowdCounting-P2PNet for crowd counting and Counting-DETR for few-shot counting.
If you try to reproduce P2PNet, please pay attention to the following bug (which is I find during my reproduction): Bug.
