[0050] Step 1: Mesh Synthesis

[0051] Mesh compositing is the process of obtaining a target mesh of ideal size and pattern from a given mesh. The geometric grid brings compositing into the geometric compositing space, so here we use some geometric methods for compositing.

[0052] (1) Cut edge matching cost

[0053] We call the line segment that intersects on a certain block a cut edge. In order to measure the distance between two cut edges, we propose a variable matching cost equation. exist figure 2 Middle e 1 , e 2 represent two sides, Represents the four vertices of two sides, and each side is directional, and in this article, it is from the in side to the out side. cutting edge e 1 to e 2 The distance of is calculated by the following formula:

Abstract

The invention provides a user interactive structural texture synthesis method. The method comprises the following steps of: firstly generating a target grid which is the same with the mode of a sample image and has the ideal size according to a grid which is input by a user or the grid extracted from the sample image, further performing texture design by adding various synthesis modes by the user, then performing initialization on the target grid according to a feature distance concept provided by the invention and finally synthesizing result texture in a parallel manner by combining with the pixel direction feature provided by the invention. According to the method disclosed by the invention, the synthesis effect against the structural texture is good, and interactive texture design and synthesis can be realized by utilizing the parallelism of a GPU (graphic processing unit) on frame rate.

Description

technical field [0001] The invention relates to the technical field of interactive design and synthesis of structural textures, in particular to a method for synthesizing structural textures interactively with users. Background technique [0002] The present invention mainly focuses on the interactive design and synthesis of textures with structural information, and recent achievements include feature-based texture synthesis, texel rearrangement, block splicing methods, and real-time texture synthesis. [0003] Feature-based texture synthesis: [0004] There are various features in texture, including shape, size, direction, texel color, etc., so many studies have focused on this in recent years. [0005] Wu et al. extracted small and easy-to-obtain distribution maps of structural features such as curves and folds from the sample image, and then matched and deformed the features to construct a large feature distribution map to complete the entire synthesis process.
