Patent ID: 8244071

Claim:
A method for scaling digital image data using a non-dyadic lifting scheme wavelet transform, the method comprising: transforming data associated with a first pixel included in the digital image data at a first position to a high-pass coefficient; transforming data associated with a second pixel included in the digital image data at a second position adjacent to the first pixel to a first low-pass coefficient; and transforming data associated with a third pixel included in the digital image data at a third position adjacent to the second pixel to a second low-pass coefficient, wherein: the first low-pass coefficient and the second low-pass coefficient are determined by different predetermined mathematical functions, one or more parameters control the transforming the data associated with the second pixel to the first low-pass coefficient and the transforming the data associated with the third pixel to the second low-pass coefficient such that an average of the first low-pass coefficient and the second low-pass coefficient is substantially the same as an average of the data associated with the second pixel and the data associated with the third pixel, and the first pixel is adjacent to the second pixel that is subsequently adjacent to the third pixel.
