The core insight behind MoSo is to determine the importance of each sample by assessing its impact on the optimal empiri…
The goal of click-based interactive image segmentation is to extract target masks with the input of positive/negative clicks. Every time a new click is placed, existing methods run the whole segmentation network to obtain a corrected mask, which is inefficient since several clicks may be needed to r…
