Original Abstract Submitted
Various factors can degrade the quality of camera images. For example, images can be distorted by rotation, shear, horizontal lens shift, and/or vertical lens shift. Such factors may result in perspective distortion of a subject being captured in a camera image by transforming horizontal and/or vertical lines of the subject and/or subject plane into lines that are at an angle to the horizon and/or the normal to the horizon in the image. Prior techniques that rely on search processes to find a homography for perspective correction in images can be time-consuming and computationally expensive. Moreover, these prior techniques may fail to find a solution that results in a corrected image of sufficient quality. The disclosed techniques overcome these drawbacks by applying fast homography transformations based on deterministic methods to align images that exhibit perspective distortion.
