Feature request: Tags that show same object should get combined instead of overlapping.

[bryanlyon]

Is your feature request related to a problem? Please describe.
There are too many redundant tags in the images. I.E. Man, Woman overlaying each other. Should be combined so that they're the same.

Describe the solution you'd like
I think that for display, overlapping tags (IOU > 90% for example) they should be listed as one bounding box, with combined ID. For example, if they're labeled as WOMAN and GIRL with mostly matching BBOXes, they should be combined to one WOMAN/GIRL tag (at least when displayed, even if they're kept separate in the DB).

Describe alternatives you've considered
They could be combined in the DB with rules allowing them to be combined into new categories For example "Brasierre" and "Swimwear" that overlap > 90% should probably be combined to "Bikini Top" or something similar. "Man" and "Boy" could become "Male person" or many other categories could be made.

IOU is a strong method to verify that the boxes aren't just somewhat overlapping, but instead referencing the same object.

Hi @bryanlyon. Thanks for submitting this request. I think Intersection over Union (IoU) could be good for this. I'm not sure about combining 2 tags in the DB as it would increase the total number of tag types overall but definitely agree the display could be improved. I think first we need to allow editing/removing of object tags in a similar way to how face tags can be then at least people can remove the one that's not so good.
