Image Upscaling and Denoising withGaussian filter inColouredImages-A Performance Analysis
Amanjot Singh, Jagroop Singh · International Journal of Engineering and Technology · 2017
The paper has been focused on the comparison of the different upscaling methods for images.Along with upscaling Gaussian filter based denoising has also been considered for images contaminated with various noises.Gaussian filter is a usual filter used in Digital image processing [1][4].Its functioning can be controlled by its kernel size.Interpolation is one of the basic methods used in image up scaling and Super-resolution.The response varies with interpolation method variation and that has been presented in the analysis.In this paper, image quality matrices like PSNR and MSE have been compared for the various noises in images.The behavior of different methods for image upscaling along with image denoising has also been included in the analysis.Moreover, Gaussian filter based de-noising method has been compared along with different types of interpolations.The paper gives a review of interpolation methods and their behavioral analysis under the influence of different noises.
