Research on the Generation of the Mosaic Picture Based on the Model Image and Small Photographs
基于模板和小图片的拼图方法探究

Mosaic pictures,stitched up from many small photographs with some special symbols or rich meanings,have already been broadly applied in advertisement,artistic designs and drumbeating.This paper presents a series of semiautomatic methods to generate this kind of pictures.This method includes a matching model,which can arrange small photographs into a mosaic with an optimization algorithm,a model modifying some less matchable photographs in the HIS color space and a series of artifices to improve the visual effect.It can be concluded from the experiments on several symbols of the 2008 Beijing olympic that the series of semiautomatic methods can make mosaic pictures well and provide the materials of a unique style,for advertisement and flacks.
