Weighted Interpolation Scheme for Robust Video Deinterlacing

Abstract

SUMMARYIn this letter, a low-cost weighted interpolation scheme (WIS) for deinterlacing within a single frame is discussed. Three useful weights measurements are introduced within the operation window to reduce false decisions on the basis of the LCID algorithm. The WIS algorithm has a simple weight-evaluating structure with low complexity, which therefore makes it easy to implement in hardware. Experimental results demonstrated that the WIS algorithm performs better than previous techniques.

“…Deinterlacing methods can be roughly classified into two categories: (1) the intra-field spatial domain methods that only use one field [4][5][6][7][8][9][10][11][12][13][14][15][16] and (2) the inter-field temporal methods that use multiple fields [17][18][19][20]. The inter-field temporal methods can provide better deinterlacing results than intra-field methods.…”
