Enhanced Forest Microexpression Recognition Based on Optical Flow Direction Histogram and Deep Multiview Network
In order to recognize the instantaneous changes of facial microexpressions in natural environment, a method based on optical flow direction histogram and depth multiview network to enhance forest microexpression recognition was proposed. In the preprocessing stage, the histogram equalization of the...
