Facial expressions of emotions can be possibly read by computer vision and machine learning system. Regarding the evidence in cognitive science, the perception of facial dynamics is necessary for understanding the facial expression of human emotions. Our previous study proposed a temporal feature to model the levels of facial muscle activation. However, the quality of the feature suffers from various types of interference such as translation, scaling, noise, blurriness, and varying illumination. To cope with such problems, we derive a novel feature descriptor by expanding 2D Gabor features for a time series data. This feature is called Cumulative Differential Gabor feature (CDG). Then, we use a discriminative subspace for estimating an emotion class. As a result, our method gains the advantages of using both spatial and frequency components. The experimental results show the performance and the robustness to the underlying conditions. <\/jats:p>","DOI":"10.1142\/s1793351x15400036","type":"journal-article","created":{"date-parts":[[2015,10,7]],"date-time":"2015-10-07T02:32:22Z","timestamp":1444185142000},"page":"193-213","source":"Crossref","is-referenced-by-count":1,"title":["Cumulative Differential Gabor Features for Facial Expression Classification"],"prefix":"10.1142","volume":"09","author":[{"given":"Prarinya","family":"Siritanawan","sequence":"first","affiliation":[{"name":"School of Information Science, Japan Advanced Institute of Science and Technology, Asahidai 1-1, Nomi, Ishikawa 923-1211, Japan"}]},{"given":"Kazunori","family":"Kotani","sequence":"additional","affiliation":[{"name":"School of Information Science, Japan Advanced Institute of Science and Technology, Asahidai 1-1, Nomi, Ishikawa 923-1211, Japan"}]},{"given":"Fan","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Information Science, Japan Advanced Institute of Science and Technology, Asahidai 1-1, Nomi, Ishikawa 923-1211, Japan"}]}],"member":"219","published-online":{"date-parts":[[2015,10,6]]},"reference":[{"key":"rf1","author":"Ambadar Z.","year":"2005","journal-title":"Psychological Science"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1109\/TNN.2002.804287"},{"key":"rf4","volume-title":"Pattern Recognition and Machine Learning (Information Science and Statistics)","author":"Bishop C.
