description The invention relates to the technical field of image processing, and in particular to an automatic portrait matting method. The automatic portrait matting method is characterized by comprising the following steps: 1, preparing: selecting a picture containing a portrait; 2, carrying out face recognition and detection: detecting the position and the size of the face in the picture through an automatic face detecting technique; 3, defining matting anchorage: defining the anchorage of the range and the region growing of the portrait in the picture through combining with the proportional relation of a face and a body in human structurology according to the position and the size of the face; and 4, carrying out portrait matting: matting the portrait starting from the anchorage through a region growing method. Compared with the prior art, the method has the advantages that the manual participation degree is reduced; the matting speed is high; the obtained portrait is more accurate; and the method is convenient for
