The methods include capturing a low resolution image of the rectangular object and detecting edges of the rectangular object in the low resolution image, where the edges form a quadrangle, calculating a coordinate of each corner of the quadrangle, calculating an average coordinate of each corner of the quadrangle in a most recent predetermined number of low resolution images, calculating a dispersion of each corner of the quadrangle in the most recent predetermined number of low resolution images from a corresponding coordinate of each calculated average coordinate, determining whether the dispersion of each corner of the quadrangle is less than a predetermined value, capturing a high resolution image of the rectangular object when it is determined that the dispersion of each corner of the quadrangle is less than the predetermined value, and geometrically transforming the quadrangle of the rectangular object in the high resolution image into a rectangle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for capturing images using a mobile device","description":"The systems and methods of the present disclosure enable a user to use a mobile device to automatically capture a high resolution image of a rectangular object.
