Abstract
The present invention relates to the automated processing of documents and, more specifically, to methods and systems for aligning, capturing and processing document images using mobile and desktop devices. In accordance with various embodiments, methods and systems for document image alignment, capture, transmission, and verification are provided such that accurate data capture is optimized. These methods and systems may comprise capturing an image on a mobile or stationary device, converting the color image into a black and white image, testing the accuracy of the image captured and transmitted, and processing the image for data extraction. Additionally, these may comprise aiding the user in capturing the image, providing geometric correction of document images, converting the image to black and white, transmitting both the images to a server, optimizing image size, analyzing images using iterative and weighting procedures, and comparing data the images to maximize data capture confidence.
