Dominant point detection based on suboptimal feature selection methods

•Turning angle curvature utilized for parameter-free dominant point selection.•For Sarkar’s criteria, our method provides the lowest ISE value as 2.43.•Besides, for Sarkar’s criteria, our method achieves the highest FOM score as 1.25. This paper presents a viable alternative solution for dominant point detection predicated on the comparison of suboptimal feature selection methods. Suboptimal feature selection methods are utilized as standard criteria to identify dominant points. Considering that all of the combinations of points comprise many sets, an algorithm that eliminates some of them is affirmed and illustrated. The sequential backward selection, sequential forward selection, generalized sequential forward selection, generalized sequential backward selection and plus l-take away r selection methods are performed on the remaining points to extract the dominant points. The simulation results exhibit that this method is significantly more effective and efficient in comparison to other proposed methods.
