Abstract
Methods, devices, and systems for capturing documents are provided. A frame in a viewfinder is selected and is converted into a binary version. Segmentation of the binarized version of the frame is performed using computed horizontal and vertical histograms. At least one document is identified in the selected frame. The at least one document is captured upon determining that values of the one or more parameters associated with the document match predetermined values of corresponding one or more parameters.
