Abstract:
Systems and methods for reconstructing a document from a series of document images. An example method comprises: receiving a plurality of image frames, wherein each image frame of the plurality of image frames contains at least a part of an image of an original document; identifying a plurality of visual features in the plurality of image frames; performing spatial alignment of the plurality of image frames based on matching the identified visual features; splitting each of the plurality of image frames into a plurality of image fragments; identifying one or more text-depicting image fragments among the plurality of image fragments; associating each identified text-depicting image fragment with an image frame in which that image fragment has an optimal value of a pre-defined quality metric among values of the quality metric for that image fragment in the plurality of image frames; and producing a reconstructed image frame by blending image fragments from the associated image frames.
