Patent number: 10803275Abstract: A method for deconvolution of digital images includes obtaining a degraded image from a digital sensor, a processor accepting output from the digital sensor and recognizing a distorted element within the image. The distorted element is compared with a true shape of the element to produce a degrading function. The degrading function is deconvolved from at least a portion of the image to improve image quality of the image. A method of indirectly decoding a barcode includes obtaining an image of a barcode using an optical sensor in a mobile computing device, the image comprising barcode marks and a textual character. The textual character is optically recognized and an image degrading characteristic is identified from the textual character. Compensating for the image degrading characteristic renders previously undecodable barcode marks decodable. A system for deconvolution of digital images is also included.Type: GrantFiled: October 4, 2018Date of Patent: October 13, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Varun Bhagwan, Timothy Liu, Justin Ormont, Heather Underwood
