Patent number: 8868265Abstract: An aircraft system and method provide visual input to a pilot during takeoff roll. A runway centerline line vector is determined from a captured image, a displacement of the aircraft from the centerline line vector and an aircraft line vector are determined from the image based on the knowledge of sensor characteristics. The runway centerline line vector and the aircraft line vector are displayed to indicate a direction in which the pilot may change heading to maintain the aircraft on the runway.Type: GrantFiled: November 30, 2011Date of Patent: October 21, 2014Assignee: Honeywell International Inc.Inventors: Ondrej Koukol, Tomas Beda, Jan Lukas

Patent number: 8855358Abstract: Apparatus and method to verify the integrity of a digital image (i.e., deciding whether or not the entire image or just a portion has been tampered with, and/or finding the doctored area in the image). One first determines the imaging sensor's reference pattern noise, which serves as a unique fingerprint that identifies the imaging sensor that captured the image. To verify the integrity of the content in a region of the image, a correlation detector determines the presence or absence of the imaging sensor's reference pattern noise in that region, thereby verifying whether or not the image has integrity. The correlation detector can also find automatically one or more regions in the image that were tampered with.Type: GrantFiled: April 16, 2012Date of Patent: October 7, 2014Assignee: The Research Foundation for The State University of New YorkInventors: Jessica Fridrich, Miroslav Goljan, Jan Lukas
