Patent number: 9317922Abstract: A system and method for recognition of images may include the use of alignment markers. The image recognized may be a pattern from an array, a character, a number, a shape, and/or irregular shapes. The pattern may be formed by elements in an array such as an identification marking and/or a sensor array. More particularly, the system and method relate to discriminating between images by accounting for the orientation of the image. The size and/or location of alignment markers may provide information about the orientation of an image. Information about the orientation of an image may reduce false recognitions. The system and method of image recognition may be used with identification markings, biosensors, micro-fluidic arrays, and/or optical character recognition systems.Type: GrantFiled: January 31, 2011Date of Patent: April 19, 2016Assignee: Board of Regents The University of Texas SystemInventors: Jason E. Meiring, Timothy B. Michaelson, C. Grant Willson
