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.
