Spherical Trigonometry and Navigational Calculations

Introduction Navigation is the process of planning, recording, and controlling the movement of a craft or vehicle from one location to another. The word derives from the Latin roots navis (“ship”) and agere (“to move or direct”). To achieve these goals in a general way, a coordinate system is needed that allow quantitative calculations. The

A New Simulation of Spiral Architecture

Introduction Hexagonal structure is different from the traditional square structure for image representation. The geometrical arrangement of pixels on hexagonal structure can be described in terms of a hexagonal grid. Hexagonal structure provides an easy way for image translation and rotation information. Spiral Architecture is a relatively new and powerful approach to machine vision system.
