1. A method, comprising: performing face detection of an image; obtaining a coarse face segmentation region of at least one face and a contour edge of the at least one face based on the face detection; searching the contour edge within a preset position adjusting range in a lateral or longitudinal direction to locate a plurality of updated contour edge points, wherein the preset position adjusting range is based upon a two dimensional coordinate of (x,y) and includes a lateral search range of (x−δ, x+δ) and a longitudinal search range of (y−δ, y+δ), wherein δ varies from one two dimensional coordinate to another, and wherein δ is selected so as to define a weight of contour edge information; and adjusting the coarse face segmentation region based on the contour edge, the weight of the contour edge information as defined by δ, and the plurality of updated contour edge points to obtain a fine face segmentation region.
