Soft computing techniques for video de-interlacing

Abstract

This paper presents the application of soft computing techniques to video processing. Especially, the research work has been focused on the de-interlacing task. It is necessary whenever the transmission standard uses an interlaced format but the receiver requires a progressive scanning, as happens in consumer displays such as LCDs and plasma. A simple hierarchical solution that combines three simple fuzzy logic-based constituents (interpolators) is presented in this paper. Each interpolator is specialized in one of three key image features for de-interlacing: motion, edges, and possible repetition of picture areas. The resulting algorithm offers better results than others with less or similar computational cost. A very interesting result is that our algorithm is competitive with motion-compensated algorithms. ; This work was partially supported by MOBY-DIC project FP7-INFSO-ICT-248858 (www.mobydic-project.eu) from European Community, TEC2008- 04920 project from the Spanish Ministry of Science and Innovation, and by P08-TIC-03674 project from the Andalusian regional Government. ; Peer Reviewed
