Hexagonal structure is a different approach to represent an image rather than the traditional square structure.Hexagonal shaped pixels are used in hexagonal structure representation of images.The hexagonal structure closely resembles the structure of human visual systems (HVS) because the photo receptors found in human retina are arranged in a hexagonal manner.Also curved structure can be well represented using hexagonal structure.So if we could able to represent the image in hexagonal domain, the computer vision will be as close to human vision.But in the present scenario there is no hardware available to capture or display hexagonal images.So we have to simulate a hexagonal grid on a regular square pixel image for further processing in hexagonal domain.In this paper, a new method for constricting a pseudo hexagonal structure using square pixel is presented.This method preserves the important property of hexagonal architecture that each pixel has exactly six surrounding neighbors.This method also preserves the equidistance property of hexagonal pixels.
