Thanks for your code. I'm decoding yolact output. I would like to know what "yolact/priors_plus.dat" of your code is for. I also wonder if this is a necessary file for decoding.

Sorry that it has been such a long time that I may not remember details very well and correctly. priors are parameters related to anchor box positions and sizes. In the train set, anchor boxes with different positions, size and aspect ratios, are scaled the same. The model itself just gives confidences for every anchor box, with normalized center positions and sizes. Thus, in the decoding process, anchor box parameters are necessary to decode the output boxes out of normalized ones.
