Abstract

The present invention discloses an optimal model based interactive image recolorating method. The method comprises nine steps of: converting a to-be-processed color image to perform manual line coloration; then separately performing matting based on global optimization and based on local optimization on the colorated image, so as to separately obtain a globally optimized matted image and a locally optimized matted image; performing binarization processing on the obtained globally optimized matted image and locally optimized matted image; combining binarized images by adopting an addition or subtraction policy according to a selected region attribute of line coloration; calculating a region that needs to be recolorated in the to-be-processed color image; converting an RGB color space of a colorated region to an HSV color space; adjusting a tone channel and a saturation channel in the colorated region in an interactive manner; converting the HSV color space of the image to the RGB color space; and finally, combining an image of which the region is reclorated with an original color image to obtain a recolorated image.

Description

[0001] technology neighborhood [0002] The invention relates to a color image recoloring method, in particular to an interactive image recoloring method based on an optimization model. Background technique [0003] Image recoloring technology refers to the process of changing the original style of the image by changing the color of the image to achieve a certain color effect. Recoloring technology usually involves many image and video processing technologies such as image segmentation, clustering, and motion estimation, which can directly generate huge economic benefits. Recoloring technology is derived from practice and is directly oriented to applications. Therefore, the current recoloring technology Research is a challenging hot topic in the neighborhood of computer graphics and computer vision, and has very broad application prospects in many engineering neighborhoods such as film and television, animation, image, and science, industry and military. The traditional recol...
