Abstract
A computer-implemented method for providing a text-based representation of a region of interest of an image to first is provided that includes a step of identifying text zones within the image, each text zone including textual content and having a respective rank assigned thereto based on an arrangement of the text zones within the image. The method also includes determining a processing sequence for performing optical character recognition (OCR) on the text zones. The processing sequence is based, firstly, on an arrangement of the text zones with respect to the region of interest and, secondly, on the ranks assigned to the text zones. The method further includes performing an OCR process on the text zones according to the processing sequence to progressively obtain a machine-encoded representation of the region of interest, and concurrently present the machine-encoded representation to the user, via an output device, as the text-based representation.
