Abstract:
1. A method for picture up-sampling from a base-layer picture comprising base-layer image samples, base L [•, •], to an enhancement-layer picture comprising enhancement-layer image samples, pred L [•, •], comprising: defining a position, (xP, yP), for an upper-left sample of a block of said enhancement-layer picture; deriving a relative location, xB, yB, xB1, yB1, of said block of said enhancement-layer picture in said base-layer picture; and producing a sample block array, pred wherein e[−2], e[−1], e[0], e[1], e[2], and e[3] represent said first set of filter coefficients for said first six-tap filter; and wherein e[−2], e[−1], e[0], e[1], e[2], and e[3] represent said second set of filter coefficients for said second six-tap filter.
