DeepVoting: A Robust and Explainable Deep Network for Semantic Part Detection under Partial Occlusion [PDF]

open access: yes, 2018
In this paper, we study the task of detecting semantic parts of an object, e.g., a wheel of a car, under partial occlusion. We propose that all models should be trained without seeing occlusions while being able to transfer the learned knowledge to deal ...
