A De-Interlacing Method for Video Surveillance in Intelligent Substation

Article Preview

Abstract:

A de-interlacing method for video surveillance in intelligent substation is presented in this paper. Firstly, a framework for performance evaluation is proposed so that the subjective performance of de-interlacing will not matter in applications such as video compression. Then pre-filtering is performed to remove potential noise, and a hierarchical structure is introduced for same-parity field pictures or opposite-parity field pictures to get more reliable optical flow results for compression. Finally the optical flow results are used to improve the accuracy of block-based methods for each partition of the to-be-interpolated image and the final motion vectors are determined. Experimental results show that the proposed solution can achieve both better peak signal-to-noise ratio (PSNR) performance and visual effects.
