MATLAB Source Code for Block-Based Texture Synthesis

This document presents a MATLAB source code implementation for block-based texture synthesis, incorporating cutting-edge advancements in the field. The algorithm operates by sampling and reassembling texture patches from a source image, utilizing overlap regions and error minimization techniques to ensure seamless transitions. Key implementation features include customizable block size parameters through variables like blockSize and overlapWidth, which control the fundamental synthesis units. The core algorithm employs dynamic programming for optimal patch matching, calculating Sum of Squared Differences (SSD) between overlapping regions to determine optimal placements. Advanced functionality includes texture optimization loops with adjustable iteration counts (maxIterations parameter) and color space transformation options for enhanced visual fidelity. Users can modify synthesis parameters through a configuration structure (config struct) that controls aspects like randomness (randomSeed), neighborhood size (neighborhoodSize), and boundary handling methods. The program outputs high-resolution synthesized textures with preservation of statistical properties and structural patterns from the original sample. This implementation serves as a robust framework for texture generation in computer graphics research, digital art creation, and material design applications, offering both preset configurations and programmable interfaces for specialized requirements.
