(English Abstract)
We investigate the problem of partitioning a histogram H with n vertices into rectangles using disjoint line segments drawn inside H. We develop a dynamic programming algorithm that computes a thick partition of H, which maximizes the minimum side length over all resulting rectangles. As subroutines, it uses algorithms that compute a thick partition of cakes and staircases, two special kinds of histograms. We observe that there always exists a thick partition of H such that the line segments constituting the partition satisfy certain conditions. Based on this observation, the algorithm computes a thick partition in O(n) time and space. The algorithm can be useful in processing digital images and designing very-large-scale integration (VLSI) layouts.
