In some case, we can easily distinguish fruit areas in a natural background image by color. However, finally, we have to use shape analysis for identification and to obtain exact boundary positions. This research aims to detect position of fruits by shape and by using elliptic Fourier descriptors to describe shape. Then, we deform the typical shape in the spatial frequency domain by scaling, rotating, and phase shifting and matching with the image to obtain the maximum likelihood. However, the matching process takes a long time owing to the inverse Fourier series and parameter deformation. To optimize these problems, we use FFT for inverting the typical shape and a genetic algorithm for searching the maximum likelihood because this is a problem dependent on the natural environment. The genetic algorithm can decrease position-searching time.","PeriodicalId":301855,"journal":{"name":"Proceedings of the 41st SICE Annual Conference.

In this method, a state point is moved onto a stable manifold of an unstable equilibrium point and the flow toward the unstable equilibrium point is utilized. In a power system, the state point is not able to stay around the unstable equilibrium point in the attractor for a long time when generators fall out of step and the OGY control input is larger than that of the other system. We improved the OGY method in order to make the best of this flow near the stable manifold. The amplitude of control inputs is limited and applied many times in the improved method. The state point is asymptotically moved on to the unstable equilibrium point and successfully controlled by a small input and without large time delay.","PeriodicalId":301855,"journal":{"name":"Proceedings of the 41st SICE Annual Conference.
