A localisation system is an essential knowledge for a mobile robot to be able to freely navigate in its world. In this paper, pose estimation and tracking of a mobile robot is presented for an indoor cluttered environment using only an overhead panoramic vision system. The method presented is fast without requiring unwrapping of the panoramic view. It is assumed that the robot's workspace is 2D planer...
Horizon detection is a pre-cursor to vision processing in air and water robotics. This paper makes three contributions to horizon detection. First, a theoretical framework for generating pseudo spectra images (PSI), from spectrum analysis of XYZ color-space is presented. Second, wavelengths in the visible spectrum are identified, at which the PSI has similar intensities for sky and clouds. Generating...
Chronic administration of antipsychotic drugs produces adaptive responses at the cellular and molecular levels that may be responsible for both the main therapeutic effects and rebound psychosis, which is often observed upon discontinuation of these drugs. Here we show that some antipsychotic drugs produce significant functional changes in serotonergic neurons that directly impact feeding behavior...
