Objective assessment on remote sensing image registration is very difficult for ground truth is rarely available and
remote sensing images are extremely complex. Little work has been done to solve this problem. In this paper, we
propose an objective and quantitative evaluation approach based on the registration curves. The speed of convergence is
measured by the ratio of half amplitude to half-bind width, and the robustness is measured by the curvature variation.
Experimental results indicate that our method is valid.
