Abstract

The invention discloses a buffing algorithm suitable for an image shot by a mobile device. The algorithm comprises the steps of S100, acquiring the original image; S200, carrying out skin color detection on the original image, generating a Gaussian pyramid of a skin color probability graph, utilizing the original image to generate a Gaussian pyramid of a grayscale image, estimating global buffing intensity of the grayscale image, and calculating a stretching coefficient table of the buffing intensity; S300, calculating a similarity matrix through the Gaussian pyramid of the skin color probability graph, the Gaussian pyramid of the grayscale image and the stretching coefficient table of the buffing intensity; and S400, utilizing the similarity matrix to carrying out buffing operation on the original image, and synthesizing a final image. According to the algorithm, automatic buffing can be realized, and a user is enabled to complete buffing by one key; and the algorithm is simple and stable, is natural in a buffing effect, and runs smoothly on the mobile device.
