IMAGE ENHANCEMENT BY SUPPRESSING WRINKLES USING L_0 NORM AND ACO

摘要

In this article the problem of enhancing the image quality by suppressing the predetermined information (wrinkles) from it is taken into account. The technique used to do this is based on the optimisation approach followed by ants while searching for good path between their colony and source of food. In addition to this another technique that is applied to enhance detail layer is based on global optimisation filter known as L_0 norm, as other filters produces halo artefacts and gradient reversal artifacts when we enlarge the gradient of the image. In this paper three parameters are taken into account in order to validate our research for enhancing the image (1) PSNR value i.e. Peak Signal to noise ratio (2) Mean Square Error (3) Histogram Equalisation.
