Abstract :
The authors describe an improved motion-adaptive de-interlacing method that incorporates the missing lines of interlaced fields from pixels of the same field or adjacent fields after motion compensation. Some improvements were obtained by suppressing the effect of false motion caused by interpolation error in the searched field, and by interpolation filtering based on the characteristics of moving objects. Experimental data show that the proposed method resulted in smaller interpolation error than conventional de-interlacing methods
