A method and system for synthesizing texture using a preprocessed exemplar image and a neighborhood-matching per-pixel texture synthesis correction technique. The sub-pass correction system and method alters pixel coordinates to recreate neighborhoods similar to those in the exemplar image. In the context of parallel texture synthesis, instead of synthesizing all pixels of an image simultaneously, the sub-pass correction system and method allows neighbors to be corrected in different sub-passes. Each pixel, therefore, benefits from the correction of some of its neighbors in previous sub-passes. This reduces the required number of global correction passes to obtain good synthesis results Generally, one or more correction passes are performed, with each correction pass divided into a plurality of correction sub-passes. A number of pixel coordinates are corrected in parallel during each of the correction sub-passes.
