Use `img = cv2.cvtColor(img, cv2.COLOR_RGBA2RGB)`

Hi. It's actually strange. Confidences shouldn't be higher than 1.0 in case initital confidences are lower than 1.0: https://github.com/ZFTurbo/Weighted-Boxes-Fusion/blob/master/ensemble_boxes/ensemble_boxes_wbf.py#L193 Can you provide some example?

WBF works great for TTA. It's bad for filtering boxes from single model. TTA != Single model

You need the following 2 functions: 1) Easy one: get intersection over union (IoU) metric for two poligons. 2) Harder: get weighted average of several polygons. I think its not...

Actually it was interesting question. I found some answer: https://gis.stackexchange.com/questions/68359/creating-average-polygon/68617 But polygons are complicated and sometimes it's hard to say what is average for 2 polygons.

First idea for the average of two polygons that comes to mind: 1) We take as a basis a polygon with a greater probability (will be number 1) 2) For...

@innat do you have some polygons you want to esnemble? I mean to prepare some small benchmark for testing.

It's too easy case with convex polygons. We need some letters I guess.

Thank you. I downloaded data. Will look into it.

@DavidAdamczyk there were 2 guys who tried to solve that problem. Unfortunately they didn't make it. If you speak russian, I made formalization of task (with some ideas and links):...
