Figure 3: Location accuracy contrast among the Forstner algorithm, CPDA, JUDOCA, and our proposed method for detected junction points. (a) The horizontal axis represents the labeled number of junction points in Figure 2(a) and the vertical axis describes the location error of the junction points detected by the Forstner algorithm, CPDA, JUDOCA, and our proposed method. (b) The horizontal axis represents the labeled number of junction points in Figure 2(c) and the vertical axis describes the location error of the junction points detected by the Forstner algorithm, CPDA, JUDOCA, and our proposed method.
