The three dimensional（ 3 D） face segmentation technology has practical significance in the field of 3 D face research. The result is important for the 3 D face feature points localization

expression recognition

facial animation

etc. Because of the shortage in precision of the existing segmentation algorithm

3 D face segmentation method based on square combination descriptor and deep forest is proposed

and segmentation experiments are carried out. The experimental results show that this algorithm is of high precision

and good segmentation results

which has practical application significance.
