Abstract
Recent developments in the field of facial expression recognition advocate the use of feature vectors based on Local Binary Patterns (LBP). Research on the algorithmic side addresses robustness issues when dealing with non-ideal illumination conditions. In this paper, we address the challenges related to mapping these algorithms on smart camera platforms. Algorithmic partitioning taking into account the camera architecture is investigated with a primary focus of keeping the power consumption low. Experimental results show that compute-intensive feature extraction tasks can be mapped on a massively-parallel processor with reasonable processor utilization. Although the final feature classification phase could also benefit from parallel processing, mapping on a general-purpose sequential processor would suffice.
