Picture Collage Synthesis Considering Theme and Visual Features

To assist designers in picture collage art creation,we propose a picture collage synthesis method considering both theme and visual features.First,given a container image and resource image set,we divide the container image into sub regions.Then,we adopt the circle packing algorithm and Delaunay triangulation algorithm to generate the sub regions’Voronoi diagram and obtain a patch set.Next,we construct a theme-color similarity matrix and calculate the mapping between resource images and patches.Finally,we apply the color linear fusion method to optimize the visual effect of the collage.While preserving the visual features of the container image,the proposed method can also guarantee similar theme information between the container image and the resource images.The comparative experiment with popular software shows that the proposed collage image synthesis method is able to achieve a more visual pleasing result and could be used potentially in the field of digital media and decoration design.
