Abstract

The era of image processing has influenced every part of the universe right from medical field to space research. Digital image enhancement is the process to improve quality metrics of a noisy image. In this presented paper based on anisotropic non-linear diffusion technique to enhance the input noisy gray scale images, here mainly focused on speckle noise, which aremainly cause by today's modern image processing sensing devices. The value of quality matrices of an enhanced image are PSNR 10 dB and SNR 11 dB. After comparison the values of image parameters with different technique, the presented work not only attained the better result but also itreduce the complexity of digital circuit as its fall under spatial domain category. Finally the paper concluded that anisotropic non-linear diffusion technique is efficient forgrey scale image enhancement, especially for reduction of speckle noise.
