What does the CLASS_AGNOSTIC mean? about fcis HOT 5 CLOSED

I think the code is a bit different from the description in the paper..... I'm not good at coding and I think the code is hard to understand....

from fcis.

It means the class-agnostic bounding box regression. All categories share same weights during the training of bbox regression.

@oh233 You mean there is only one single mask and bbox for a RoI, and the class is given by the score? So the mask and bbox are not chosen from the C+1 maps.. And I still think CLASS-AGNOSTIC should be false when doing instance segmentation.. May be setting it to True is good for performance?

from fcis.

Only the bbox regression is class-agnostic, not the mask. Mask and classification scores are still selected from C+1 maps (21 for VOC) and bbox are selected from 2 maps (foreground/background).

@oh233 Got it, thanks.
