摘要: The present invention discloses a face contour extraction method. method comprises the steps of: 1) after inputting an image, employing detection algorithm to extract area, and finding approximate area of through key feature point location algorithm; 2) performing sampling along generate series dense squares toallow whole be included in squares; 3) each local square extracting one parabola guide curve based on gradient information form result set formed by curves; 4) fusing redundancy curves into global obtain complete line fusion PCA. is high precision fast speed, can automatically perform user interaction, finally obtained ishigh with pixel level meets features parabolic shape.
