Abstract: Systems and methods are presented for acquisition of receipt information using portable scanning devices such as a cellphone camera running suitable software. A smartphone having associated software is used to capture image from a receipt, by holding the smartphone camera over the receipt such that the latter is within the field of view of the cellphone camera. The software may be adapted to automatically identify receipts when such appear in the camera's field of view, and to automatically capture images. Compositing multiple images, image stitching, and OCR are all employed as necessary by the system to extract textual information from receipts.
