Abstract

Texture synthesis is the process of taking small samples of a texture and generating a large amount of image data which will be perceived by the human eye to be the same texture. In other words, to take a texture and find a way to expand it into a wider area so that it can be used for texture mapping and texture based rendering of larger objects.

In this project I utilize and compare two techniques for synthesis:

The first technique is an image-based method in which a new image is synthesized by stitching together small patches of existing images. This process is called image quilting. Quilting is a texture synthesis algorithm which produces good results for a wide range of textures. I then use an expansion of the algorithm to perform texture transfer – rendering an object with a texture taken from a different object. The method works directly on the images and does not require 3D information.

The second technique is a stochastic system for non-periodically tiling the plane with a small set of Wang Tiles. The tiles are filled with texture that when glued together create a continuous image. The main advantage of using Wang Tiles is that once the tiles are filled and a tile set is ready, large textures can be created very efficiently at runtime.
