A method for doing interactive image processing operations on large images.

摘要

A method of performing interactive image processing of a digital image with a digital computer by: 1. forming an operations log of each operation that is to be performed on a digital image; 2. determining which pixels of the digital image must be computed (operated) upon in order to obtain the output image by processing through the operations log in a reverse direction; 3. ordering the computation of the determined pixels in a way which minimizes the amount of computer memory needed by forming chunks of dependent pixels and by calling from memory only those chunks which are needed for the final result and by deleting used chunks when they are no longer needed; and 4. processing through the operations log in a forward direction. i
