ABSTRACT:
A method of reconstructing an image, where the input image data is preferably part I or part II compliant JPEG2000 coded data, or pixel data of the original image. The method selects (810) an output resolution R, and then determines a number of sub-passes to extract from each block code based on the selected resolution. The method then extracts (830) the determined sub-passes and the remaining sub-passes are discarded. The method then reconstructs840the image from the extracted sub-passes. The reconstructed image can be in the form of the selected resolution of the original image, or it can be in the form of compressed image data of the selected resolution of the original image.
