In this paper, we propose a novel hybrid de-interlacing algorithm, which effectively combines two motion-compensated (MC) de-interlacing techniques: MC Median Filtering (MCMF) and Adaptive Recursive (AR) with one spatial approach: Line Averaging (LA). Despite of its drawbacks, AR is one of the best methods nowadays. MCMF helps reduce flickers and LA is very robust to erroneous motion vectors. The interpolation switches among these methods based on the proposed measurement of texture smoothness and motion vector (MV) reliability. MCMF is adopted when MV is reliable and texture is rich. LA is used when MV is unreliable and texture is smooth. AR is applied to the remaining regions. Experimental results show that the proposed algorithm is superior to the compared algorithms in terms of peak signal-to-noise ratio (PSNR) and that the de-interlaced videos have very high subjective quality.
