Problems solved by technology

[0004] The icon segmentation algorithm in the related art generally adopts the interactive acquisition of the sample points of the foreground and the background, then respectively builds models for the sample points of the foreground and the background, and finally integrates the edge information of the image, and adopts the method of Graph-cut (image segmentation) Optimize the algorithm to perform binary segmentation on the image, the algorithm itself is more complicated
Moreover, because the icon segmentation algorithm in the related art does not analyze the content of the icon, it must interactively obtain the sample points of the foreground and the background, and needs to make a judgment for each pixel, so the efficiency of the algorithm is relatively low, and it cannot meet the needs of mobile devices for icon segmentation. Real-time requirements for segmentation

Abstract

The invention provides a method and device for icon segmentation. The method comprises the steps of performing image pre-segmentation on a target icon according to color characteristic values; calculating significance values of each color area after image pre-segmentation; distinguishing the foreground and the background of the icon according to the significance values; and segmenting the foreground and the background of the icon. According to the method and device for icon segmentation, efficiency of an image segmentation algorithm can be improved, and the image segmentation algorithm can be applied to a mobile device in real time.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an icon segmentation method and device. Background technique [0002] The so-called image segmentation refers to the process of subdividing an image into multiple image sub-regions (a collection of pixels), the purpose of which is to simplify or change the representation of the image, making the image easier to understand and analyze. [0003] The current image segmentation technology on mobile devices has been greatly developed in recent years. With the enhancement of multimedia information processing capabilities on mobile devices, how to efficiently and accurately perform automatic binary segmentation of images, and then quickly apply the segmentation results to various aspects of image processing is the direction of research and development. [0004] The icon segmentation algorithm in the related art generally adopts the interactive acquisition of the s...
