摘要:

分形是多数图形图像系统的重要组成部分,主要应用于图像的建模与绘制,然而已有的单一IFS模型无法对复杂场景图像建模。针对具有局部自相似特征的场景图像,提出了纹理与IFS结合的TIFS模型对其建模,其中IFS描述场景的外形结构,纹理表示场景中的细节。从真实图像中提取TIFS,并进行TIFS变形,可以实现图像的变形,又由于分形变形具有吸引子大小、变形方向和移动位置可控的特点,基于真实图像的TIFS变形具有连续的、真实感的效果。

关键词: 分形, 分形变形

Abstract:

Fractal appears in most of the graphics system, and widely used for image modeling and rendering. However, the existing single IFS method always fails in modeling complex scenery image. In this paper, we proposed a new fractal method, named TIFS (Texture based IFS), to model a sort of local similarity scenery image. IFS and texture indicate scenery's structure and details respectively. TIFS model is extracted from a scenery image result in a continuous sequence of similar images, and then it is morphed. Because the IFS attractors' size and moving direction is well controlled through the whole morphing procedure, the morphing of scenery image with TIFS method has continuous and reality effect.
