Micro-expression detection using integral projections

Abstract : Automatic detection of micro-expression from a video is the first step in the micro-expression analysis. In this paper, we present a method addressing the micro-expression detection problem based on the differences in the Integral Projection (IP) of sequential frames. The method can detect the temporal location of the micro-expression. It involves an observation of the Chi-squared distance of the IP to measure the difference between frames. The main advantage of using IP for micro-expression detection is its low computation cost, which brings an important merit in real-time application. To evaluate our method, experiments are completed on two micro-expression databases namely CASME and CASME II. Results on these two datasets show that the proposed method obtains positive promising results with much less computation time against state-of-the-art methods. © 2017, Vaclav Skala Union Agency.
