      Implementation of Some Speckle Filters on Digital Image and OCT Image

      Optical Coherence Tomography (OCT) technology introduces speckle, an insidious form of multiplicative noise. Reduction of speckle noise is one of the post processing techniques to increase the quality of OCT images. Some of the existing speckle denoising filters were applied on digital image and on OCT image and their performances are compared in this paper. The objective evaluation of both the types of images was performed using various image metrics like peak signal to noise ratio, root mean square error and image quality index. The obtained results have been presented by filtered images, statistical tables and graphs.
