A joint Mapping and Synthesis approach for Multiview Facial Expression Recognition

Mahdi Jampour and Mohammad-Shahram Moin

Congrats and thanks to Dr. Moin for his collaboration on our recently accepted paper with the title of "A joint Mapping and Synthesis approach for Multiview Facial Expression Recognition" in prestigious peer-reviewed journal of International Journal of Pattern Recognition and Artificial Intelligence (IJPRAI).



This paper presents a novel approach to address pose-invariant face frontalization aiming Multiview Facial Expression Recognition (MFER). Particularly, the proposed approach is a hybrid method, including both synthesizing and mapping techniques. The key idea is to use mapped reconstructive coefficients of each arbitrary viewpoints and the frontal bases where the mapping functions are provided by learning between frontal and non-frontal faces' coefficients. We also exploit sparse coding for synthesizing the frontalized faces, even with large poses. For evaluation, two qualitative and quantitative assessments are used along with an application of multiview facial expression recognition as a case study. The results show that our approach is efficient in terms of frontalizing non-frontal faces. Moreover, its validation on two popular datasets, BU3DFE and Multi-PIE, with various assessments contexts reveal its efficiency and stability on head pose variation, especially on large poses.
