Problems solved by technology

[0004] However, this image cropping method needs to generate thousands of candidate cropping frames and determine the probability value corresponding to each candidate cropping frame one by one. Therefore, for a single image to be cropped, it takes a long time to determine the cropping frame. low efficiency

Embodiment Construction

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0061] The embodiment of the present invention provides an aesthetics-based image cropping method, which can be applied to electronic devices, such as servers of image search websites, smart phones, and personal computers. Based on this method, the server can crop the image uploaded by the user, and obtain an image with high aesthetic quality under the premise of retaining the semantic information contained in the original image. The smart phone can obtain the captured current image...

Abstract

Embodiments of the present application provide an aesthetics-based image clipping method and apparatus, which belong to the field of computer technology. The method comprises the following steps: obtaining an image to be cut; calculating a saliency map corresponding to the image to be cropped according to a saliency detection algorithm, wherein the saliency map comprises a saliency image corresponding to the image to be cropped, the saliency image being a gray-scale image; determining a saliency boundary box in the saliency map by a saliency region extraction algorithm; determining a salient region corresponding to the salient boundary box in the image to be cropped, wherein the salient region is an image region contained in the salient boundary box in the image to be cropped; determiningan aesthetic region boundary box containing the salient region according to an aesthetic region identification algorithm and the salient region; a target image being obtained by cutting that image tobe cut based on the boundary frame of the aesthetic region. By adopting the invention, the efficiency of determining the cutting frame can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an aesthetics-based image cropping method and device. Background technique [0002] In addition to containing semantic information, images also have aesthetic qualities. An image with high aesthetic quality can better express the semantic information of the image and is more liked by users. However, with the popularization of digital cameras and smart phones, most of the images on the Internet are taken by users without professional photography knowledge, and the aesthetic quality of the images is low. Therefore, obtaining images with high aesthetic quality based on images in the web has become a hot research issue. [0003] Since the image composition is an important factor affecting the aesthetic quality of the image, people generally change the image composition by cropping the image, thereby improving the aesthetic quality of the image. The processing flow of t...
