Embodiment Construction
[0097] In this example, if figure 1 As shown, a facial expression recognition method based on partially occluded images includes the following steps:
[0098] 1, a kind of facial expression recognition method based on partial occlusion image, it is characterized in that carry out as follows:
[0099] Step 1, preprocessing the face images containing N types of expressions in the face expression library of known categories:
[0100]Use the AdaBoost face detection algorithm to detect the face area in all the face images to obtain the face image; then use the two-way gray scale integral projection method to locate the eyes of the detected face images, and locate the people after positioning The face image is subjected to scale normalization processing to obtain a pure face image set; in this embodiment, the pixel size of all face images after scale normalization processing is 96×96;
[0101] Take the pure face image set as the sample set, select a part of samples of each person ...
