Many researchers conducted the effort for improving the classification accuracy of satellite image. Most of the study has used optical spectral information of each pixel for image classification. By applying this method for high resolution satellite image, number of class became increase. This situation was remarkable for objects in urban area. In this study, we propose the method for extractin...

Let S be a flat surface, such as the Euclidean plane. We obtain direct characterizations of the connected components of the space of all curves on S which start and end at given points in given directions, and whose curvatures are constrained to lie in a given interval, in terms of all parameters involved. Many topological properties of these spaces are investigated. Some conjectures of L. E. D...

In this article, we consider the motion planning of a rigid object on unit sphere with speed. The is constrained by maximum absolute value, $$U_{max}$$ , geodesic curvature its path; constrains to change heading at fastest rate only when traveling tight smaller circular arc radius $$r <1$$ where r depends bound, . We show in article that if $$0<r\le \frac{1}{2}$$ shortest path between any two c...
