针对同一幅合成图像的不同区域间,如何实现纹理图案的多尺度连续变化,提出一种基于像素的多尺度纹理合成算法.在逐像素点合成的基础上,通过为已知匹配点建立一个到连续的多分辨率样图的正向映射,并重新采样合成像素点,实现合成结果的任意尺度连续渐变的可控性.实验证明该方法不增加大量的处理时间,并可适用于大多数基于样图的逐点合成方法.

In a single image generated from texture synthesis, the texture pattern scale is expected to be nonhomogeneous for time to time. With this ideal, this paper presents a simple and efficient texture synthesis algorithm that user can control the basic pattern scale varying from big to small or from small to big consecutively in different location of a single image. In the process of synthesis pixel by pixel, it constructs a positive direction map to multi-resolution textures for the best-match pixels. Through resampling these pixels, it can control the synthesis result arbitrarily. Experiment proves that the algorithm is free from suffering vast extra process time and easy to code, and it also can be applied to most synthesis algorithms that synthesize a texture one pixel at a time.
