Abstract

The present invention discloses an intelligent photo clipping method and device. The method comprises the following steps: a photo image of an intelligent device is obtained; a plurality of sub-regions are generated in the photo image, the aesthetic scores of the sub-regions are calculated, and an optimal aesthetic clipping area is obtained according to the aesthetics scores; and the photo image is clipped according to the coordinates of the optimal aesthetic clipping area. According to the intelligent photo clipping method and device provided by the embodiments of the invention, the intelligent clipping of a photo is realized through picture aesthetic evaluation technology, so that a clipped photo can better accord with an application scene from the perspective of aesthetics. The types of photos to which the intelligent photo clipping method and device can be applied are more universal. The intelligent photo clipping method and device of the invention have the advantages of convenient operation, high efficiency and high industrial utilization value. With the intelligent photo clipping method and device of the invention adopted, defects in the prior art can be eliminated.
