A method is provided for decompressing an image originally compressed usi ng a known compression technique. An original compressed image file is defin ed by a plurality of locations that correspond to image data. A set of smoot h test images is created by iteratively applying a plurality of different si ze PIXON® kernels to each location of a starting image beginning with a smal lest size kernel. Each smooth test image is compressed using the known compr ession technique, then compared against the original compressed image at eac h location of the image to determine a goodness- of-fit of the compressed sm ooth test image to each location of the original compressed image file. For each location, the smooth test image that has the largest size kernel that p asses a pre-determined goodness-of-fit criterion is selected for a given loc ation of the decompressed image. A compression method utilizes the PIXON® me thod for optimization of knot points within an image. The optimized knot poi nts are used to interpolate image intensity between the knot points.
