Abstract
Linear space-invariant image-restoration algorithms often introduce ringing artifacts near sharp intensity transition areas. This paper presents a new adaptive post-filtering algorithm to reduce the ringing artifacts. The proposed method extracts an edge map of the image using autocorrelation. On the basis of the edge information, ringing artifacts are detected and removed by an adaptive bilateral filter. Experimental results show that the proposed algorithm can efficiently remove ringing artifacts with edge preservation.
