1 COMPARISON BETWEEN K_SVD AND OTHER FILTERING TECHNIQUE Anuj Kumar Patro Manini Monalisa Pradhan Gyana Ranjan Mati Swasti Dash Abstract The field of image de-noising sometimes referred to as image deblurring or image (de-convolution) is concerned with the reconstruction or estimation of the encrypted image from a blurred and noisy one.. SVD process is then employed for the noisy images in order to remove noise from the input images. The noisy image is divided into patches. The SVD denoising process is applied to the identified patches in the images. The objective of the paper is to perform analysis of different types of non linear filters and calculate their PSNR, FSIM value according noise density. keyword:k- SVD, PSNR, FSIM I.INTRODUCTION Noise elimination is a main concern in computer vision and image processing. A digital filter [1] is used to remove noise from the degraded image. As any noise in the image can be result in serious errors. Noise is an unwanted signal, which is manifested by undesirable information. Thus the image, which gets contaminated by the noise, is the degraded image and using different filters can filter this noise. Thus filter is an important subsystem of any signal processing system. Thus filters are used for image enhancement, as it removes undesirable signal components from the signal of interest [2]. The process of image denoising process is implemented based on the SVD algorithm for the efficient removal of noises in the images[3]. Initially noise is added to the images based on the random noise generated. The dictionary is created for the images in order to identify the noise locations in the images. The clustering process groups the noise locationsin the images based on the difference in the noise locations in the images. Optimization of images is based on the Low Rank optimization process. Finally, structured sparse representation is employed for the images to reconstruct the high-resolution images. The performance of the process is measured with the help of performance metric like PSNR, FSIM. II.METHODS There are basically two noises considered such as Gaussian noise and impulse noise. Several noise density like low (0.4) has been implemented.[4]. Likewise the Gaussian noise with variance 0.01 and has been evaluated using standardize (boy.bmp) image of size 256*256 and of bit 8 bit is take-in in to the consideration. Filter add used for de-noising the image corrupted with impulse noise [5]The performance can be analyzed through the basic PSNR and FSIM matrices[6].the quality of denoised image can be calculated by the highest peak 335
2 signal noise ratio PSNR=10 log 10 2 as proposed algorithm has ability to reduce the high density of the noise. The process of image denoising process is implemented based on the SVD algorithm for the efficient removal of noises in the images[6]. = Patch grouping process is employed based on Initially noise is added to the images based on the measurement of similarity identification based random noise generated. The dictionary is created for clustering of the patches based on Fuzzy C means. the images in order to identify the noise locations in Fuzzy C means process identifies the pixels that were the images. The clustering process groups the noise similar and groups them into a single cluster. locations in the images based on the difference in the In the back propagation process, the noises in the noise locations in the images. Optimization of images images occurring due to the pixel grouping based on is based on the Low Rank optimization process. the low rank approximation are Finally, structured sparse representation is employed removed.[10].performance of the enhancement for the images to reconstruct the high-resolution process is measured based on the PSNR and FSIM images. The performance of the process is measured calculation [11]. with the help of performance metric like PSNR, FSIM The calculated performance metrics indicates that the [7]. proposed method is more efficient compared to the Input SVD patch image Denoising grouping Back propagation Performance Measures Optimization calculated dictionary based on SVD process is then optimized resulting in the patch grouping process. The optimization process is employed based on Low rank approximation process. The low rank approximation process minimizes the overall errors in the obtained de-noised image.

CONCLUSION In this paper, we focused on the image denoising through non-linear filters which have reduced the complexity some to extend. The non-linear filter does not applicable for all the noises and not permeable to restore the original properties. In this paper Image denoising through K-SVD algorithm is presented as well as comparison with other filters are done by taking the standardize image. The performance matrices PSNR and FSIM have been calculated. The K-SVD algorithm reduces the complexity. REFERENCES [1] C. Kervrann and J.
