Abstract: Images in bitonal formats often include watermarks, stamps, or other patterns and artifacts. These patterned artifacts may be represented as a series of geometric points, dots, and/or dashes in the general shape of the original pattern. These patterned artifacts make other processes such as optical character recognition (OCR) difficult or impossible when items or pixels of interest are also found within the pattern of such artifact(s). Current patterned artifact removal solutions use methods of erosion to minimize the unwanted patterned artifact. However, such methods also erode the pixels/items of interest which, in turn, cause failures in other processes, such as OCR, that are desired to be carried out on or with the image.

Abstract: The present disclosure relates to a computer-implemented system and method for finding matching occurrences of an item of interest (or image or sub-image) within a document (or larger image) via cross correlation and setting a dynamic threshold for each document (or larger image). The described system and method are capable of matching and locating the one or more items of interest within each specific document (or larger image).

Abstract: The subject invention is a cooling system of an internal combustion engine having a wet-sleeve cylinder liner that improves heat reduction efficiency as compared with traditional cylinder liners. The improved liner has an outer surface with a plurality of peaks and valleys. The peaks and valleys create an increased surface area of the outer surface thereby increasing contact with a cooling medium and more efficiently reducing heat within the engine. The peaks and valleys are positioned along the entire length of the cylinder liner and are generally arcuate in a sinusoidal pattern. The liner also includes an inner surface of the liner that remains generally planar for receiving a piston. Finally, one end of the liner also includes a flange for mating the liner to a counterbore of the engine.
