Mobile document capture assist for optimized text recognition

1. A method of providing a visual cue for improved text imaging on a mobile device, the method comprising:

determining, by a processing device operably connected to a mobile device, a minimum text size for optical character recognition (OCR) of an image captured by the mobile device;

receiving, by an image capturing device operably connected to the mobile device, an image stream of a printed substrate of a document;

comparing, by the processing device, a size of a visual cue and the minimum text size for optical character recognition; and

displaying, on a display operably connected to the mobile device, the image stream and the visual cue superimposed onto a portion of a white space of the document in the image stream, wherein the size of the visual cue is based on the minimum text size.

2. The method of claim 1 , further comprising notifying, by the processing device, a user of the mobile device when text displayed within the image stream is at least as large as the minimum text size.

3. The method of claim 2 , wherein the notifying comprises altering the visual cue, outputting a sound, causing a haptic feedback, or altering the image stream.

4. The method of claim 1 , further comprising determining, by the processing device, a size of the visual cue based upon image capturing device resolution, display resolution, and OCR engine operational requirements.

5. The method of claim 1 , further comprising capturing, by the image capturing device, a digital image of the image stream, wherein the digital image does not include the visual cue.

6. The method of claim 1 , wherein the visual cue comprises a geometric shape or an interactive cue.

7. The method of claim 1 , further comprising determining, by the processing device, a position of the visual cue within the image stream based upon an analysis of the image stream captured by the capture device.

8. The method of claim 7 , wherein the analysis of the image stream comprises minimizing interference between the visual cue and printed content being captured, wherein minimizing the interference comprises:

determining a portion of the document that is free of text content; and

positioning the visual cue in the portion that is free of text content.

9. The method of claim 1 , wherein the visual cue comprises a bounding box.

10. The method of claim 1 , wherein the visual cue comprises a text string.

11. A mobile device comprising:

a processing device;

a display operably connected to the processing device and having an associated display resolution;

an image capture device operably connected to the processing device and having an associated image capture resolution; and

a non-transitory computer readable medium in communication with the processing device, the computer readable medium comprising one or more programming instructions for causing the processing device to:

determine a minimum text size for optical character recognition (OCR) of an image captured by the mobile device,

receive an image stream of a printed substrate of a document as captured by the image capture device,

compare a size of a visual cue and the minimum text size for optical character recognition, and

display the image stream and the visual cue superimposed onto a portion of a white space of the document in the image stream on the display, wherein the size of the visual cue is based on the minimum text size.

12. The mobile device of claim 11 , wherein the one or more instructions further comprise instructions for causing the processing device to output a notification to a user of the mobile device when text displayed within the image stream is at least as large as the minimum text size.

13. The mobile device of claim 12 , wherein the notification comprises altering the visual cue, outputting a sound, causing a haptic feedback, or altering the image stream.

14. The mobile device of claim 11 , wherein the one or more instructions further comprise instructions for causing the processing device to determine a size of the visual cue based upon the image capture resolution, the display resolution, and OCR engine operational requirements.

15. The mobile device of claim 11 , wherein the one or more instructions further comprise instructions for causing the processing device to capture a digital image of the image stream, wherein the digital image does not include the visual cue.

16. The mobile device of claim 11 , wherein the visual cue comprises a geometric shape, a bounding box, or an interactive cue.

17. The mobile device of claim 11 , wherein the one or more instructions further comprise instructions for causing the processing device to determine a position of the visual cue within the image stream based upon an analysis of the image stream captured by the capture device.

18. The mobile device of claim 17 , wherein the instructions that cause the processing device to analyze the image stream further comprise instructions for causing the processing device to minimize interference between the visual cue and printed content being captured.

19. The mobile device of claim 18 , wherein the instructions that cause the processing device to minimize the interference comprise instructions for causing the processing device to:

determine a portion of the document that is free of text content; and

position the visual cue in the portion that is free of text content.

20. The mobile device of claim 11 , wherein the visual cue comprises a text string.
