As describe in question, I met one issue. For example, for a person's instance segmentation, there might be more than 1 polygon in the mask. some holes appeared in the person's polygon? How to solve this occasion? @waspinator

You may create a copy of original mask and perform morphological dilation, closing or floodfill and then use skimage.measure.find_contours() to get polygon. However, at training time you may use the original mask for the model because your requirement of getting a polygon depicting the outer boundry of the object is fullfilled by the annotations created earlier.

Same question，one polygon seems unable to cover these situations: 00000 00020
