Analysis of Image Deblurring Techniques with Variations in Gaussian Noise and Regularization factor
Image blur is integral part of imaging system and it often ruin the resultant image, video signal and photograph. Image Deblurring and Restoration is necessary in digital image processing. Many methods have been proposed in this regard and in this paper we will examine different methods and techniques of Deblurring. The analysis of these methods has been carried out on the basis of subjective and objectives results with varying various factors like regularization and WGN variance. The different methods of deblurring have tested for different spectrum of images. The results have compared with each method and based on comparative results particular method has been suggested for suitable applications. The point spread function has utilized to deblur the blurry images by changing different parameters which help to estimate amount of blur need to remove from blurry image. The performance of various deblurring techniques have evaluated based on MSE and PSNR.[1,2,3].
