A Simple Optimal Representation for Balanced Parentheses
We consider succinct, or highly space-efficient, representations of a (static) string consisting of n pairs of balanced parentheses, that support natural operations such as findi...

An enhanced perturbing algorithm for floorplan design using the O-tree representation
Recently, a deterministic algorithm based on the O-tree representation has been proposed. This method generates excellent layout results on MCNC test cases with O(n3 ) complexity,...

Monogenic Binary Pattern (MBP): A Novel Feature Extraction and Representation Model for Face Recognition
A novel feature extraction method, namely monogenic binary pattern (MBP), is proposed in this paper based on the theory of monogenic signal analysis, and the histogram of MBP (HMB...
