摘要：Emotions are most widely represented with eye and mouth expressions. The proposed system uses colour images and it is consisted of three modules. The first module implements skin detection, using Markov random fields’ models for image segmentation and skin detection. A set of several coloured images with human faces have been considered as the training set. A second module is responsible for eye and mouth detection and extraction. The specific module uses the HLV colour space of the specified eye and mouth region. The third module detects the emotions pictured in the eyes and mouth, using edge detection and measuring the gradient of eyes' and mouth's region figure
