Image deblurring – Wiener filter versus TSVD approach

Abstract

This paper presents comparison study of two different deblurring methods: Wiener filter and TSVD decomposition. Wiener filter is a method giving the best results when variance of the noise incorporated in blurring process is known a priori. In TSVD decomposition the knowledge of precise variance of the noise is not necessary to image restoration. The paper also discusses basis blurring forms and their mathematical description.
