  In current interactive instance segmentation works, the user is granted a
free hand when providing clicks to segment an object; clicks are allowed on
background pixels and other object instances far from the target object. This
form of interaction is highly inconsistent with the end goal of efficiently
isolating objects of interest. In our work, we propose a clicking scheme
wherein user interactions are restricted to the proximity of the object. In
addition, we propose a novel transformation of the user-provided clicks to
generate a weak localization prior on the object which is consistent with image
structures such as edges, textures etc. We demonstrate the effectiveness of our
proposed clicking scheme and localization strategy through detailed
experimentation in which we raise state-of-the-art on several standard
interactive segmentation benchmarks.
