Abstract
A processor implemented method includes: calculating edge direction information of edge component pixels extracted from an input image; determining an inlier pixel among the edge component pixels based on the edge direction information and virtual horizontal line information; estimating a rotation reference point based on the inlier pixel; and correcting localization information of the apparatus based on the estimated rotation reference point.
