Satellite Image Restoration Using Bilateral and Guided Filters
Authors(3) :-C. VamsiKrishna, S. Narayana Reddy, P. Jagadamba While capturing and transmitting of satellite images, due to channel effects or uncertain conditions the received images are highly degraded. These effects introduce different noise such as, Additive White Gaussian Noise, Salt & Pepper Noise and Mixed Noise. To remove these noise different types of filters are used. In the previous methods, these noise patterns are removed by using Recursive Least Square (RLS) adaptive algorithm. The implementation of this methodology is being carried out by estimating the noise patterns of unknown noise and noise patterns are eliminated by configuring Signal Enhancement with RLS algorithm. The restored images are functioned for further denoising and enhancement techniques. The performance is evaluated by means of quantitative measures in terms of MSE, RMSE & PSNR. In proposed methodology we are using the bilateral and guided filters which is used for removal of noise more effectively than the previous methods. These filters will smoothen the images while preserving edges. In blateral filtering each pixel is replaced by the weighted average of its neighbor pixels, but in guided filter the behaviour at edges will be more efficient than the bilateral filter. The performance of the proposed method is measured by means of image parameters as seen in previous methods. By comparing these values and output images, proposed method shows the efficient restoration of noisy images.
