Painting rendering method based on colour feature study

Abstract

The invention provides a painting rendering method based on colour feature study. The method comprises the following steps of: firstly, definitely defining some colour features for deciding the colour motion and colour style of a reference template mathematically; providing a study mechanism based on optimum with respect to the features, abstracting the optimization problem into a bipartite graph matching model to solve the problem by adopting a classical KM algorithm. The invention provides an after-treatment technique based on image division to ensure the continuous result in the space with respect to some pseudo boundary effect probably occurring in the result. Finally, in the drawing processing, the invention provides a new colour mixing model on the traditional framework to control the drawing accuracy better without selecting a great amount of parameters.

Description

technical field [0001] The present invention relates to a painting rendering method based on reference, in particular to a painting rendering method based on color feature learning. Background technique [0002] As digital entertainment is more and more favored by the public, computer stylized rendering technology has increasingly become a research hotspot. However, in order to render the target image into a desired style, users usually need to master and adjust a large number of parameters, which is very inconvenient for their use. Template-based computer rendering technology alleviates this problem to a certain extent, which allows users to provide an additional artwork as a reference template, and render the target image according to certain characteristics of the reference template to obtain the desired style and characteristics. [0003] Traditional template-based computer rendering techniques often focus on learning the texture features of reference images, and have a...

Problems solved by technology

[0004] Some traditional color transfer techniques can be used to transfer colors from one image to another, however these techniques only emphasize the simple transfer of colors without clearly defining which features determine the color style and mood of a reference template , so the color emotion of the reference template usually cannot be fully expressed, and some very important properties of the target image itself, such as the relationship between light and shadow, are often destroyed, resulting in image distortion
