PDPTA '04 International Conference 3' Virtual Spiral Architecture

Spiral Architecture is a relative new and powerful approach to machine vision system. The geometrical arrangement of pixels on Spiral architecture can be described in terms of a hexagonal grid. However, all the existing hardware for capturing image and for displaying image are produced based on rectangular architecture. It has become a serious problem affecting the advanced research on Spiral Architecture. In this paper, a novel mimic Spiral Architecture called virtual Spiral Architecture is presented. Using virtual Spiral Architecture, images on rectangular architecture can be smoothly transferred to hexagonal architecture. Moreover, such mimicking operation does not introduce distortion and reduce image resolution, which is an advantage over other mimicking methods. There is no doubt that virtual architecture will be helpful to research on Spiral Architecture and other hexagonal architectures. 1
