Abstract:
1. A method for decompressing an image originally compressed using an industry-standard compression method, the method comprising: inputting an original compressed image file having a plurality of locations corresponding to image data into a processor having a memory and software stored therein for decompressing an image and executing a PIXON® method; decompressing the original compressed image using a corresponding industry-standard decompression method to produce an original decompressed image data file; initializing the PIXON® decompressed image with the industry standard decompressed file; smoothing the original decompressed image using the smallest kernel selected from a plurality of different kernels to produce a first smooth test image; compressing the first smooth test image using the industry-standard compression method; comparing the first compressed candidate image to the original compressed image file to determine a goodness-of-fit within a predetermined tolerance at each of the plurality of locations within the original compressed image file; accepting the first smooth test image as the PIXON® decompressed image for each location at which the goodness-of-fit is within the predetermined tolerance and leaving the PIXON® decompressed image unchanged at all other locations; performing the steps of smoothing and comparing for each remaining kernel of the plurality of different kernels to produce a plurality of different candidate images, wherein, following each iteration, the corresponding smooth test image is accepted as the PIXON® decompressed image at each location at which the goodness-of-fit is within the predetermined tolerance and all other locations are left with the previous PIXON® decompressed image, and wherein the resulting PIXON® decompressed image remains after the final iteration; storing the resulting PIXON® decompressed image in the memory; and outputting the resulting PIXON® decompressed image to display device.
