Filter designing for digital image enhancement Using filter masking with optimization technique
Publication Date : 05/10/2017
Image enhancement techniques provide a way to improve the object identification in underwater environment. The images that are taken beneath the sea waves must be pre-processed because of disturbances in the sea water. When we capture such images, quality of images degrade due to many factors like ripples in water, lack of availability of light, organic matter dissolved in water etc and also such images are captured from a very small distance , so the images must be pre processed before applying any kind of operation on these images. To improve the quality of image the image is passed through filters. Various kind of filters up-to a precision are available till now. In this paper a masking filter technique has been proposed to clarify such images. To get the clarified results ant colony optimization has been used to detect the edges in the image. Proposed technique has been compared with existing filter in terms of PSNR and MSE.
