ABSTRACT A new processing scheme for large high-resolution displays such as Videowalls

optional enhancement algorithm; its hardware implementation requires a low computational
cost. The deinterlacing algorithm is motion-adaptive. A simple hierarchical three-level
motion detector provides indications of static, slow and fast motion to activate a temporal FIR
lter, a three-tap vertico-temporal median operator and a spatial FIR lter respectively. This …
