一个基于图片缝合的纹理迁移算法的设计与实现

An the Design and Implementation of the Algorithm of Image Quilting for Texture Synthesis

纹理综合是根据现有的一块小的输入纹理,然后通过某种算法,使之生成与小纹理类似的一块大纹理。一般要求两块纹理有较高的相似度,并且在视觉上没有生硬的拼接的感觉。此外还要求算法能有比较快的速度,有较强的实用性。图像缝合是一种快速的纹理综合算法,现在已经有一些成熟的算法,它是在把输入纹理分块之后,然后在目标图像上根据相似度进行贴图,在贴图完成之后,再对块与块之间的边界进行调整,使之实现自然过渡。该文研究的是在VC++6.0环境下通过面向对象编程用图像缝合技术实现快速纹理综合。自己设计并实现了实验系统,验证了Alexei A.Efros和William T.Freeman的纹理缝合算法,取得比较好的实验结果。

According to a piece of the existing small input texture,use some sort of algorithm to generate a big texture similar as the small input texture.It generally requires that the two textures are with high texture similarity.The result texture should be without the visual sense of blunt splicing,and the algorithm can also achieve a relatively fast speed.Image quilting is a fast texture synthesis algorithm.There are a number of sophisticated algorithms about texture synthesis.The procedure is like that: dividing the input texture into the blocks,and then mapping in the target image according the similarity between the target image and the block.After completion of mapping,adjusts the boundary between the two conjoint blocks to achieve a natural transition.This study was conducted in VC + +6.0 environments using the object-oriented programming to test Alexei A.Efros and William T.Freeman’algorithm"Image Quilting for Texture Synthesis and Transfer".The experimental results show a relatively good effect.
