“…Hence, least square fitting cannot be directly used to post-process the initial road centerline network. In order to solve the problem, the Harris corner detection approach [43,55] is used to decompose the initial road centerline network into the road centerline segment. The approach recognizes corner points according to the average gray change, which is calculated by moving a local windows in different directions and can be expressed as follows:…”

“…Invariance to scale is advantageous to only an extent and becomes a stone in the shoe, in case of large scale variations. The disadvantage of this detector is it is not invariant to large scale change [8]. Harris detector reveals the Ljunctions and points with the higher curvature along with the corner points for which second moment matrix and corner function is computed [5,6] .If both of the Eigen values of the second moment matrix are approximately equal and have high value then the taken point is detected as the corner point.…”

“…The Harris corner is a representative point feature due to its illumination insensitivity and rotation invariance. The corner feature is applied in remote sensing image registration [ 29 , 30 ]. Pei et al [ 31 ] improved the Harris corner to solve the corner clustering problem and accelerate the registration speed.…”
