Emotion Recognition Using PHOG and LPQ features

Dhall, Abhinav; Asthana, Akshay; Goecke, Roland; Gedeon, Tamas (Tom)


We propose a method for automatic emotion recognition as part of the FERA 2011 competition. The system extracts pyramid of histogram of gradients (PHOG) and local phase quantisation (LPQ) features for encoding the shape and appearance information. For selecting the key frames, K-means clustering is applied to the normalised shape vectors derived from constraint local model (CLM) based face tracking on the image sequences. Shape vectors closest to the cluster centers are then used to extract the...[Show more]
