Embodiment Construction

[0043] The present invention will be described in detail below with reference to the accompanying drawings.

[0044] figure 1 is a flowchart of the present invention. Such as figure 1 As shown, the present invention is mainly divided into 10 steps:

[0045] Step 1: Input the target image to be drawn.

[0046] Step 2: Input the stroke texture style template to be imitated, and indicate the most representative stroke area with a rectangular box in the template, such as figure 2 shown on the left.

[0047] figure 2 is a schematic diagram, the left half of which presents the most representative stroke texture area to be imitated by the style template and framed.

[0048]Step 3: According to the two-dimensional empirical mode decomposition technique (N.Huang, Z.Shen, S.Long, M.Wu, H.Shih, Q.Zheng, N.Yen, C.Tung, and H.Liu, "The empirical mode decomposition and the hilbert spectrum for nonlinear and non-stationary time series analysis,” Proceedings of the Royal Society of L...

Abstract

The invention provides a painting rendering method based on stroke texture analysis. In the invention, real stroke textures of different styles are analyzed and molded, and corresponding rendering techniques are designed, which enables a rendering system to support a greater variety of drawings. In terms of stroke texture analysis, different stroke texture styles can be correctly described and identified by making a behavioral analysis on the first two modes obtained by bidimensional empirical mode decomposition (BEMD). During the rendering process, expressive ability of traditional rendering methods is extended, and corresponding modules are designed to express stroke texture styles, which enables the rendering system to support a greater variety of drawings.

Description

technical field [0001] The invention relates to a reference-based painting rendering method, in particular to a painting rendering method based on stroke texture analysis. 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, with the continuous enhancement of rendering technology, different users usually hope to render target images in different styles to meet individual needs. [0003] Traditional computer drawing technology usually abstracts the style into a series of drawing parameters defined by stroke size, direction, stroke strength and stroke arrangement, which can express different drawing styles. However, after observing the actual paintings and communicating with artists, it is found that there are still a large number of painting styles that are similar in the above four aspects, but have very different visual effects.
