Abstract
Polygonalization is a way to approximate curves by straight-line segments. All the polygonalization methods use thresholds to produce the extreme points of the straight lines used in the approximation [1],[2],[3]. The method here introduced does not use thresholds to select the points. Ant Colony Optimization (ACO) is an optimization paradigm that mimics the exploration strategy of a colony of ants [4]. Images containing bi-dimensional shapes have been considered in this work. The goal is to find a good polygonal approximation of the contours of these images. The ants travel on segments connecting the points of the contours. Two points define a path in the ant travel. The points number of the polygonal approximation (num_steps) is user-defined. Last point connects with the first one. The two catheti AB and BC in Fig. 1 are a better curve approximation than the hypotenuse AC. AB + BC is longer than AC.
