Abstract :
We develop a new framework of multitree dictionaries which include many previously proposed dictionaries as special cases. We show how to efficiently find the best object in a multitree dictionary using a recursive dynamic programming algorithm. We apply our framework to find the best rectangular tiling of an image domain.
