摘要: A pyramid is a stack of image representations with decreasing resolution. Many processing algorithms run on this hierarchical structure in O(log(n)) parallel steps where n the diameter input image. Graph pyramids are made successively reduced graphs embedded plane. Such overcome main limitations their regular ancestors. The used may be region adjacency or dual graphs. This paper reviews different data structures and introduces new representation named combinatorial pyramid.
