一种具有光照效果和透视效果的图像纹理替换方法

从单幅图像出发，研究图像上具有光照效果和透视效果的图像纹理替换问题。这种方法对于国际互联网上建筑装修时建筑材料的选取有着一定的实际意义。首先提出了一种保持透视效果的图像纹理替换方法，使得替换后的纹理具有与透视相近似的效果，其次讨论了纹理替换后，图像的光亮度和周围环境的统一问题，给出了对替换后纹理进行光亮度调整的方法和实验结果。使用这种方法进行纹理替换的优点在于：替换后的纹理不但保持原有图像的透视效果而且保持原始图像的光照效果，所采用的方法计算量较小、并可实现纹理扩张的效果。实验结果说明该方法是可行的。

A NOVAL IMAGE TEXTURE SUBSTITUTION WITH SHADING EFFECT

Texture substitution of a single image with shading and perspective effect is discussed in this paper. This method is very useful for material selection of fitting up buildings on Internet. Firstly, a method of image texture substitution with perspective effect is presented, and then texture substitution with shading effect is discussed. The advantages of this method are its abilities of keeping perspective effect and shading effect of the original image with features of less computing cost and texture extension. The experimental results show that the algorithm is feasible.
