Abstract

The invention provides an interactive cutout system, method and device based on super-pixel segmentation, which includes: a super-pixel segmentation module: performs super-pixel segmentation on the input original image to obtain a super-pixel segmentation map; and an interactive user input response module : Display the user touch input area and the affected cutout range on the superpixel segmentation map, and respond to the user touch input event to obtain the user input area; Area filling module: Fill the superpixels of the superpixel segmentation map in the user input area with a transparent color , get the cutout result. The use of super-pixel segmentation technology can segment images more precisely than traditional methods; the combination of touch screen operation and super-pixel segmentation technology avoids the over-segmentation problem of super-pixel segmentation itself and the inaccuracy of touch screen matting, achieving It achieves the effect of precise cutout on the touch screen.

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...
