System and method for identification of sparse patterns in image data using disjoint template matching

A method uses a sparse test pattern to identify a spatial relationship between a printhead and an image receiving surface in a printer. The method includes operating a plurality of ejectors in the printhead to form a printed marks on the image receiving surface, generating image data of the test pat...

Summary:A method uses a sparse test pattern to identify a spatial relationship between a printhead and an image receiving surface in a printer. The method includes operating a plurality of ejectors in the printhead to form a printed marks on the image receiving surface, generating image data of the test pattern, and applying a predetermined disjoint template to the image data to identify a location of the printed marks. The disjoint template matching process improves the accuracy of identifying the printed marks in noisy image data and for sparse test patterns.
