Linear interpolation for image conversion between square structure and hexagonal structure

Spiral Architecture (SA) is a relatively new and powerful image structure consisting of hexagonal pixels arranged in a onedimensional coordinate system. However, all the existing hardware for capturing image and for displaying image are produced based on traditional square image structure. In this paper, we present a software approach to represent an image on SA based on linear interpolation method. We perform edge detection on SA to demonstrate the advantages of image processing on SA. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
