Using query-by-sketch we propose an application to efficiently create collages from image collections. Using rough color strokes that represent the target collage, images are automatically retrieved from a database and segmented to synthesize a new image. The database is indexed using simple geometrical and color features for each region, and histograms that represent these features for each image. The image collection is queried by means of rough strokes on a simple paint tool. The individual segments retrieved are added to the collage using Poisson image editing and alpha matting.
