Puzzle Image Mosaic

We present a new technique to produce composite images called Puzzle Image Mosaic (PIM). The method is inspired by Jigsaw Image Mosaic (JIM), where image tiles of arbitrary shape are used to compose the final picture. The JIM approach leads to impressive results, but the required computation time is high. We propose an algorithm that produces good results in lower time. The technique takes advantage from recent results about data structures aimed to optimize proximity queries. Experimental results prove the soundness of our method.
