Abstract [en]

The visual processing in the real world is different from the digital world. Monkey’s and a human’s visual world is richer and more colourful affording sight of flies, regardless of whether they are immobile or airborne. The study of the evolutionary process of our visual system indicates the existence of variationally spatial arrangement; from densely hexagonal in the fovea to a sparse circular structure in the peripheral retina. Normally we use a rectangular grid for the processing of images. But as per the perspective of the human eyes, the new approach is to change the grid from rectangular to hexagonal. Applying hexagonal grid in image processing is very advantageous and easy for mimicking human visual system. The main advantages for using the hexagonal structure in image processing is its resemblance to the arrangement of photoreceptors in the human eyes.
