Character count determination for a digital image
First Claim
1. A method comprising:
- in an electronic device comprising a memory for holding document image data and processor in communication with the memory, the processor;
receiving a financial document image;
identifying a text chunk in the financial document image according to a first image processing system wherein the text chunk has a chunk start column and a chunk end column;
beginning with the chunk start column and continuing until the chunk end column is reached, identifying a character of the text chunk, without recognizing any particular character in the text chunk, by;
determining a first column of a character as the character start column based on a number of black pixels in the column; and
determining a second column of a character as the character end column based on a number of white pixels in the column; and
,incrementing a character count value when a character end column is determined.

Abstract
An image processing system or electronic device may implement processing circuitry. The processing circuitry may receive an image, such as financial document image. The processing circuitry may determine a character count for the financial document image or particular portions of the financial document image without recognizing any particular character in the financial document image. In that regard, the processing circuitry may determine a top left score for pixels in the financial document, the top left score indicating or representing a likelihood that a particular pixel corresponds to a top left corner of a text character. The processing circuitry may also determine top right score for image pixels. Then, the processing circuitry may identify one or more text chunks using the top left and top rights scores for pixels in the financial document image. The processing circuitry may determine a character count for the identified text chunks.

9. A method comprising:
-
in an electronic device comprising a memory for holding document image data and processor in communication with the memory, the processor; receiving a financial document image; identifying a character of the financial document image, without recognizing any particular character in the financial document image, by; dividing the financial document image into a pixel array; determining a first column of a character as the character start column based on a number of black pixels in the column; and determining a second column of a character as the character end column based on a number of white pixels in the column; and
,incrementing a character count value when the character end column is determined. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method, comprising:
-
in an electronic device comprising a memory for holding document image data and processor in communication with the memory, the processor; receiving a first instance of a financial document image; identifying a text chunk in the first instance of the financial document image according to a first image processing algorithm; determining a character count of the text chunk without recognizing any particular character in the text chunk according to a second image processing algorithm; determining whether the character count meets a minimum character count threshold; where the character count does not meet the threshold, requesting an image source to communicate a second instance of the financial document image; and where the character count does meet the threshold, performing a third image processing algorithm on the first instance of the financial document image. - View Dependent Claims (17, 18, 19, 20)
