Hi, thank you for raising this question.
Actually, ignore_mask
or ignore_mask_mix
does NOT contain any groundtruth information. It only marks the padded region during image pre-processing (resizing and cropping). As for the line ignore_mask[mask == 254] = 255
, the value 254
in mask
is only labeled by the padding practice. We use value 254
to distinguish the padded region from the manual defined ignored region (value 255
in Pascal).
Therefore, we do NOT use the semantic information in mask
, and do NOT use the ignored region (value 255
) defined by manual anotators in mask
.
