Patent ID: 7433530

Claim:
A method for the scaling of image data, wherein the method is performed by a computer in association with at least one computer program embedded in a computer readable medium, the method comprising: receiving, by the computer in association with the at least one computer program embedded in the computer readable medium, n-dimensional real data, wherein the n-dimensional real data is the image data in real domain; performing, by the computer in association with the at least one computer program embedded in the computer readable medium, an (n−m)-dimensional forward transform on the n-dimensional real data to produce hybrid data, where 1≦m<n; and scaling, by the computer in association with the at least one computer program embedded in the computer readable medium, the hybrid data in p dimensions to produce scaled hybrid data representing a desired p-dimensional change in the n-dimensional real data where p≦m, wherein the image data is scaled as a result of the receiving, the performing, and the scaling being performed.
