Hi @ckchng , I add an faster version DetEval.py by polygon computing based on shapely. After testing with prediction uploaded in this comment(I have converted .mat format to .txt format as requested, see no_expand_txt.zip.

the speed boosting is significance:

slow version: about 10 min for 300 testing image
faster version: within 1 min

precision: I have uploaded the result of no_expand_txt.zip, see result.txt and ori_result.txt, which have almost the same precision, recall and F1 measure.

By the way, python3 is supported in my version with a few codes adding, hope you like it!
