Facial decomposition for expression recognition using texture/shape descriptors and SVM classifier

作者:

Highlights:

• An automatic and appropriate facial decomposition with ROIs for FER.

• Emotion representation using texture, shape-based descriptors and their combination.

• LTP descriptor analysis with new definitions and strategies for thresholding.

• Comprehensive evaluation and comparison to state of the art on 4 public databases.

• Our method outperforms all the compared methods, and is competitive with one method.
