Abstract:
1. A method for image processing, the method comprising: identifying an image processing graph comprising a plurality of nodes, each of the plurality of nodes corresponding to an image processing operation, wherein the image processing graph is adapted for generating an output image based on an input image; receiving input image data relating to a particular input image; receiving region of interest data defining an output image region to be generated based on at least a portion of the input image data; traversing the graph in a first traversal order to determine a domain of defined node output data for each of the plurality of nodes using the input image data; storing an identification of the first traversal order, wherein the stored identification of the first traversal order identifies a first sequence of the plurality of nodes; and traversing the graph in a second traversal order to determine a region of requested node output data for each of the plurality of nodes using the region of interest data, wherein the second traversal order includes a second sequence of the plurality of nodes, different from the first sequence, and the second traversal order is determined based at least in part on the stored identification of the first traversal order.
