Segment-based Methods for Facial Attribute Detection from Partial Faces

no code implementations10 Jan 2018 Upal Mahbub, Sayantan Sarkar, Rama Chellappa

Taking several facial segments and the full face as input, the proposed method takes a data driven approach to determine which attributes are localized in which facial segments.

Partial Face Detection in the Mobile Domain

no code implementations7 Apr 2017 Upal Mahbub, Sayantan Sarkar, Rama Chellappa

The three detectors following this approach, namely Facial Segment-based Face Detector (FSFD), SegFace and DeepSegFace, discussed in this paper, perform binary classification on each proposal based on features learned from facial segments.
