Methods for Photomosaic Generation Based on Different Image Similarity and Division Strategies

摘要

Photomosaic is an image that is composed of small images called tiles. In our work, different measurements of similarity between tiles in the desired original image and alternative tiles in the database are used in the generation of photomosaic after classifying tiles in the original image into tiles of purity and edge. And a heuristic position searching strategy is proposed to keep the original length-width ratio of each tile in the photomosaic generated unchanged if tiles in the database have different sizes.
