I have a question.\nabout evaluation.
\n\n> It is important to distinguish apparel category, fine-grained attributes as well as object instances. If the mask is correct but the class associated with the mask is wrong, or the mask is correct but the associated attributes are wrong, then it is considered a false positive.
\n\nwhat does mean?
\n\ne.g)
