a) (b) (c) (d) Figure 1 : A simple freehand sketch is automatically converted into a photo-realistic picture by seamlessly composing multiple images discovered online. The input sketch plus overlaid text labels is shown in (a). A composed picture is shown in (b); (c) shows two further compositions. Discovered online images used during composition are shown in (d). Abstract We present a system that composes a realistic picture from a simple freehand sketch annotated with text labels. The

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.
