Dominant Points Detection Using Phase Congruence

This paper proposes a new method for simplifying a 2d shape boundary based on its phase congruence and the optimisation of a function criterion. The phase congruence is a dimensionless feature that stands out boundary salient structures over different scales allowing a hierarchical fast optimisation process over the detected structures. The proposed method has been compared with other two well-known methods using an objective measure of the quality of the generated approximation. The experimental results have shown that the the proposed method is superior in performance to those reviewed in our study.
