Abstract

Enhancement of digital images plays a vital role in the processing of digital imaging. Especially data obtained from satellite, remote sensing, medical imaging, foreignsic science etc. Literature revealed that a number of enhancement techniques are available for square lattices, but very less work is available for the enhancement of hexagonal lattice structure. In this paper our research work is implementation of existing enhancement techniques on another structure called hexagonal lattice structure. From the simulation results, it has been investigated that the enhancement of hexagonal pixels shows high Peak Signal to Noise Ratio (PSNR) and Low Mean Square Error (MSE) and better image quality as compared to square lattice structure.
