Title: Image Denoising by Enhancing K-SVD Algorithm

Author: Endra Oey, Edwin Junius, Reza Alfiansyah, and Rinda Hedwig

Abstract: This research focused on enhancing K-SVD (EKSVD) algorithm to get optimum denoising process for an image. The new algorithm used emphasizes dictionary learning process in which it can reduce the noise at 0.05% low which almost equal to ordinary K-SVD algorithm. Moreover, EKSVD was able to reduce the time process for denoising for 40% faster than the ordinary K-SVD algorithm.

Keywords: Image denoising, K-SVD algorithm, enhanced K-SVD algorithm, optimum, dictionary learning.
