Claim One:
1. A computer-implemented method comprising: receiving an original image comprised of a plurality of pixels, the image having a plurality of undefined pixels and a plurality of defined pixels; recursively down sampling, using a processor, the image by a sampling factor to produce a plurality of down sampled images until the last down sampled image produced at each recursive down sampling instance lacks undefined pixels; storing, using the processor, each recursively down sampled image, wherein the last down sampled instance is a smallest down sampled image; recursively up sampling, using the processor, each one of the down sampled images by the sampling factor to create an up sampled image from the respective down sampled image; and at each recursive up sampling instance, pasting, using the processor, a next recursively occurring down sampled image on top of the up sampled image to create the next recursively occurring image for up sampling, wherein said pasting comprises: identifying one or more portions of the next recursively occurring down sampled image that comprises undefined pixels; and replacing the identified undefined pixels with the defined pixels of a corresponding portion of the up sampled image.
