Micro Expressions (MEs) are unique facial expressions when individual experiences an emotion but intentionally tries to hide their genuine emotion. MEs are involuntary and spontaneous, and their recognition has gained a significant research interest due to their potential applications. However, Micro Expression Recognition (MER) is an arduous task due to its short duration, subtle and local movements of faces. This paper proposes an effective descriptor called Composite Local Binary Pattern on Three Orthogonal Planes (CLBP-TOP) for Micro Expressions Recognition to address these problems. We also propose a novel Aggregated Optical Flow Vectors (AOFVs) Computation mechanism where the neighbour optical flows in a particular period are aggregated to measure motion intensities. Based on these motion intensities, we compute a weight matrix, and it is multiplied with CLBP-TOP histogram features to get weighted histogram features. For classification purposes, we employ the Support Vector Machine (SVM) algorithm. Extensive experimental evaluation of the CASME II dataset shows that our proposed approach significantly improves recognition accuracy and shows superior performance than the state-of-art methods.
