基于图片的镶嵌画是一种非实景渲染技术，是指根据目标图片的轮廓和色彩特征，将小幅图片无缝镶嵌拼接为一幅新的目标图片，镶嵌的目标图片从远处看仍然保持原有目标图片的特征。典型的镶嵌过程包括区域切分、图片匹配和镶嵌。通常采用的大规模图片数据库可以明显提升图片镶嵌效果，但也增加了镶嵌准备的难度。针对该问题，提出了以四叉树（QT）方法切分目标图片、以自组织映射（SOM）聚类方法处理小型数据库中的图片，并从中选择匹配的图片来镶嵌目标图片的构造方法。这种可控的目标图片切分、数据库图片选择以及镶嵌的多种变化可以在保持镶嵌图片外观的前提下产生多种不同的、优美的镶嵌画。

Image-based mosaic is a non-photorealistic rendering technique(NPR), which trans-fers cells of a target image with a group of tile images while preserving the overall appearance of the target image. A typical mosaicing algorithm includes cell partition and search of a large data-base for tile images most similar to the cell images. Generally, a large scale image database can en-hance the aesthetic effect, but requires much preparation time. This paper proposes a controlled mosaic method. The target image is partitioned into cells of different sizes using a quadtree meth- od. Tile images from a very small self-organizing map clustered database are selected to fill the cells. Without shortcomings of the previous methods, cell partition and tile image selections are processed in a controllable manner in the proposed method to generate different mosaics and vari-ants without losing aesthetic effect.
