Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] refer to figure 1 , a fast texture synthesis method based on LBP features in the present invention, comprising the following steps: the texture synthesis problem can be described as: given a texture sample map FI(x, y), the image size is Wf×Hf, according to FI(x, y) to generate a new texture image OT(x,y) of size Wo×Ho.

[0042] In the process of texture synthesis, the size of the texture block is a very important parameter, which directly affects the generation effect of the final image. In previous methods, it is generally set in advance or determined on the spot through an interactive method. These processing methods are not suitable for real-time processing systems, so the present invention first analyzes the texture samp...

Abstract

The present invention provides an LBP feature-based rapid texture synthetic method. The method comprises the steps of firstly selecting an appropriate texture block size automatically via a statistical method, then using the LBP feature values of an equivalent model to substitute for the gray values to carry out the block matching, wherein there is only existed 59 kinds of the LBP feature values of the equivalent model, the kind number is one order of magnitude less than the kind number of the original gray values, so that the searching matching can be carried out rapidly, and an appropriate image block can be found to fill an output image. The method provided by the present invention is simple and practical, is small in complexity, can process various texture sample images real-timely, and has the very good practical value.

Description

technical field [0001] The invention belongs to the technical field of digital image processing and computer vision, in particular to a fast texture synthesis method based on LBP features. Background technique [0002] Texture synthesis is a texture rendering technology developed to solve the problems of seam aliasing and texture acquisition in texture mapping. Such methods can generate similar textures of any size from a small sample of an input texture. It has important application value in three-dimensional realistic display, virtual reality, image restoration, etc., and has been widely concerned in the fields of computer graphics, computer vision and image processing. [0003] At present, there are mainly two types of texture synthesis methods: procedural texture synthesis and pattern-based texture synthesis. Procedural texture synthesis is also called physical simulation. It directly generates textures on the surface through the simulation of the physical generation p...
