WebThe polyphase and bicubic algorithms allow scaling to be performed in such a way as to preserve sharp edges, but without losing the smooth interpolation effect on graduated areas. For down scaling, a long polyphase filter can reduce aliasing effects. The bicubic and polyphase algorithms use different mathematics to derive their filter coefficients.
