Abstract

The invention provides an interactive matting system, method and device based on superpixel segmentation, and the system comprises a superpixel segmentation module which carries out superpixel segmentation of an inputted original image, and obtains a superpixel segmentation image; an interactive user input response module which is used for displaying a user touch input area and an affected mattingrange on the superpixel segmentation image and responding to a user touch input event to obtain a user input area; and a region filling module which is used for filling the superpixels of the superpixel segmentation image in the user input region with transparent color to obtain an image matting result. Compared with a traditional method, the super-pixel segmentation technology can segment the image more finely; through combination of touch screen operation and a superpixel segmentation technology, the problem of excessive segmentation of superpixel segmentation and the defect of inaccurate touch screen matting are avoided, and the effect of accurate matting on the touch screen is achieved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an interactive matting system, method and device based on superpixel segmentation. Background technique [0002] Image matting is an important technology in image and video processing, and it has been widely used in photo processing, movie special effects and home entertainment. [0003] For high-precision image matting in the existing technology, it usually needs to rely on special shooting techniques in the early stage and a large number of manual matting. For example, it is necessary to shoot against a solid-color background such as a green screen to facilitate post-processing image processing. For photos with complex backgrounds taken in natural scenes, professional retouchers need to use professional retouching software to manually cut out the pictures. [0004] The patent with the publication number of CN 108683865A discloses a background replacement syst...
