A wireless wearable device that operated by Android phones to measure and record the skin moisture of human face is proposed in this paper. The skin moisture of human face is measured as a resistance by a simplified Electrochemical Impedance Spectroscopy. The interdigital electrode is used to contact skin directly, and also conducts square wave signal to skin surface. However, skin moisture attenuated...
In this paper, we consider the problem of robust facial expression recognition and propose a novel scheme for facial expression recognition under facial occlusion. There are two main contributions in this work. Firstly, a novel method for facial occlusion detection based on robust principal component analysis (RPCA) and saliency detection performs efficiently to detect facial occlusions. Secondly,...
