In robot navigation tasks, such as unmanned aerial vehicle (UAV) highway traffic monitoring, it is important for a mobile to follow specified desired path. However, most of the existing path-following algorithms cannot guarantee global convergence paths or enable following self-intersected due existence singular points where return unreliable even no solutions. One typical example arises in vec...

For image structure representation and feature extraction, the curling vector field transform is proposed based on the magneto-static analogy. The digital image is taken as the source of the vector field, and the vector field transform of the image is presented imitating the form of the physical magnetic field, which has a distinctive feature of rotating whorl pattern. The simulation results in...
