Segment-based Methods for Facial Attribute Detection from Partial Faces

Upal Mahbub, Sayantan Sarkar, Rama Chellappa

State-of-the-art methods of attribute detection from faces almost always assume the presence of a full, unoccluded face. Hence, their performance degrades for partially visible and…
