Abstract: Aspects of the present disclosure propose techniques for reconstructing a document mosaic using video streams of the document. The streams provide information identifying a layout that relates sequential frames of a video to each other. Once the streams are captured using a mobile device, it is then possible to reconstruct a virtual view of the entire document as though it were taken with a single camera shot. The reconstructed virtual view of the document will be suitable as input to an optical character recognition engine, which can be used for translating the document.
