[0028] The specific examples and effects of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] refer to figure 1 , the present invention is based on fast expression information extraction and the facial expression synthetic method of Poisson fusion and mainly comprises the following steps:
[0030] Step 1, according to the position difference of the salient feature points of the face of the source object with the neutral expression and the non-neutral expression, the shape template of the salient feature points of the face of the target object with the non-neutral expression is obtained.
[0031] The present invention uses the Multi-PIE dataset as a multi-expression face dataset. The Milti-PIE dataset contains 337 objects, and each object has 15 kinds of attitude information and 20 kinds of lighting conditions. According to the different collection times, each collection time Nodes collect different facial expressio...
