Analýza a Syntéza textur

Abstract

This thesis focuses on example-based texture synthesis and analysis. Synthesis describes the way in which an image of required dimensions is created from a texture of insufficient dimensions to correspond to defined requirements. The first part of the thesis describes textures, their categorising used for comparison of generated results and how to map the textures on surfaces of objects. Furthermore, main algorithms of currently used methods for texture synthesis are listed and described. Selected methods from patch-based category were implemented and practically compared within the thesis. The next part of the thesis contains descriptions of Image Quilting and Graphcuts methods. Part of the thesis is a modification of Image Quilting method using algorithms for edge detection in an image and modification of Graphcuts method allowing its acceleration. The conclusion of the thesis deals with difficulties occurring during the texture synthesis and suggestions of their solutions.
