摘要
用具有特殊象征意义或丰富内涵的小图片拼接成与模板图像逼近的大图片,在广告制作、艺术设计、文化宣传等方面有着广泛的应用价值。为实现这一目的,提供了一套半自动拼图的方法,其中包括小图片到模板图的匹配优化模型、对匹配欠佳图片的HIS空间变换修正模型以及一系列改善视觉效果的优化处理技巧。对2008年北京奥运会的若干标志图形的实验证明,这套方法可以较好地实现拼图效果,可为广告设计、文艺宣传等提供别具一格的素材。
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 flaeks.
