Blotch detection and removal is an important issue for archive film restoration. In this work, a two-stage Simplified Ranked Order Difference (SROD) detector that takes local motion changes into consideration has been proposed to increase blotch detection performance. Furthermore a novel pixel-based correction method that determines the new values of blotched pixels from spatio-temporal correlation considering edge information is developed. Experimental results show that the proposed approaches give successful detection and correction performances and outperform previously proposed techniques.read more

On pixel-based texture synthesis by non-parametric sampling
TL;DR: The objective is to enhance texture quality as much as possible with a minor sacrifice in efficiency in order to support the conjecture that the pixel-based approach would yield high quality images.
