Non-positive Face Chin Detection Method Based on Curve Fitting

The head recognition system needs precise contours of the face area, whereas the non-positive face color contours often contain neck areas, which will seriously affect the extraction of contour features. Therefore, the neck area in the outline of the human face needs to be removed to obtain the final facial contour. In this paper, the chin curve is fitted based on the extremum of the contour features of the left and right sides of the human chin region, and then the neck area can be removed. The experimental results show that the method proposed in this paper can obtain the non-positive face profile without the neck.
