"Photosketch": semiautomatische Erstellung von Internet-Bildmontagen

Es mutet wie ein April-Scherz an: mittels einer Skizze und einigen Suchbegriffen soll "Photosketch" - eine Forschungsarbeit der fünf Informatikstudenten Tao Chen, Ming-Ming Cheng, Ping Tan, Ariel Shamir und Shi-Min Hu, die an den Universitäten Tsinghua und Singapur - Bilder aus dem Internet zusammensuchen, Objekte extrahieren und in einem neuen Bild nahtlos zusammensetzen. Das Projekt wurde soeben auf der "Siggraph Asia 2009" erstmals vorgestellt.

Aus dem Abstract: "We present a system that composes a realistic picture from a simple freehand sketch annotated with text labels. The composed picture is generated by seamlessly stitching several photographs in agreement with the sketch and text labels; these are found by searching the Internet. Although online image search generates many inappropriate results, our system is able to automatically select suitable photographs to generate a high quality composition, using a filtering scheme to exclude undesirable images. We also provide a novel image blending algorithm to allow seamless image composition. Each blending result is given a numeric score, allowing us to find an optimal combination of discovered images. Experimental results show the method is very successful; we also evaluate our system using the results from two user studies."
