Abstract
A document processing apparatus comprises a scanner for scanning a bank check to obtain gray scale image data associated with the bank check. A processor is provided for (i) selecting one of a plurality of binarization programs based upon the gray scale image data, and (ii) applying the binarization program selected to at least a portion of the gray scale image data to provide a binary image of at least a portion of the bank check.
Claims20
A document processing apparatus comprising:
- a scanner for scanning a bank check to obtain gray scale image data associated with the bank check;
- a memory for storing a plurality of different selectable binarization programs, each of the plurality of different selectable binarization programs having a non-selectable threshold associated therewith;
- and
- a processor for (i) selecting one of the plurality of different selectable binarization programs based upon the gray scale image data associated with the bank check, and (ii) then applying the selected binarization program to at least a portion of the gray scale image data to provide a binary image of at least a portion of the bank check.
A method of processing a bank check, the method comprising the steps of:
- (a) scanning the bank check to obtain gray scale image data associated with the bank check;
- (b) selecting one of a plurality of different selectable binarization programs having non-selectable thresholds based upon the gray scale image data obtained in step (a);
- and
- (c) applying the binarization program selected in step (b) to at least a portion of the gray scale image data obtained in step (a) to provide a binary image of at least a portion of the bank check.
A document processing apparatus comprising:
- a scanner for scanning a bank check to obtain gray scale image data associated with the bank check;
- a memory for storing a plurality of different selectable binarization programs, each of the plurality of different selectable binarization programs having a single predetermined threshold associated therewith and
- a processor for (i) selecting one of the plurality of different selectable binarization programs based upon the gray scale image data associated with the bank check, and (ii) then applying the selected binarization program to at least a portion of the gray scale image data to provide a binary image of at least a portion of the bank check.
A method of processing a bank check, the method comprising the steps of:
- (a) scanning the bank check to obtain gray scale image data associated with the bank check;
- (b) selecting one of a plurality of different selectable binarization programs having fixed predetermined thresholds based upon the gray scale image data obtained in step (a);
- and
- (c) applying the binarization program selected in step (b) to at least a portion of the gray scale image data obtained in step (a) to provide a binary image of at least a portion of the bank check.
