Abstract
A document image that is the source of Optical Character Recognition (OCR) output is displayed. Recognition confidence parameters are determined for regions of the document image corresponding to words in the OCR output. The regions are displayed in a manner (e.g., highlighted in various colors) that is indicative of the respective recognition confidence parameter. Preferably, a user can select a region of the displayed document image. When the region is selected, text of the OCR output corresponding to the selected region is displayed in a pop-up menu.
