Implement three measures

[InstantWindy]

Hello ,did you use the official code to calculate Region Similarity and Contour Accuracy? If so,I have a question about the official code "jaccard.py" file and the "f_boundary.py" file.But I don't know what the input parameters of the db_eval_iou function of the'jaccard.py'file and 'db_eval_boundary' function of the 'f_boundary.py' file should be? Thank you!
