1. A processor-implemented method for detecting a signature, comprising:
- using a processor for;
accessing a negotiable instrument image, the negotiable instrument image in a first digital image format;
converting the negotiable instrument image from the first digital image format to a second digital image format;
dynamically determining a maximum pixel count threshold by sampling multiple areas in the converted negotiable instrument image;
counting a number of a type of pixels in a signature window of the converted negotiable instrument image to generate a signature window pixel count, wherein the type of pixels comprise dark pixels;
comparing the signature window pixel count to the maximum pixel count threshold; and
determining a potential signature error when the signature window pixel count is greater than the maximum pixel count threshold.

Abstract
A system, method and computer-readable medium are provided to enable digital bank endorsement. A digital image of a back side of a check may be placed in a computer memory. Appropriate coordinates for a bank endorsement may be determined. A bank endorsement may be automatically generated. The digital image may then be electronically altered by overlaying, merging, or rendering text of the generated bank endorsement. A modified digital image may be combined with an image of the front side of the check and stored and/or exported to check clearing operations.

10. A system for detecting a signature on a negotiable instrument, the system comprising:
-
a memory including processor-executable instructions; and a processor in communication with the memory and configured, when executing the processor-executable instructions, to; access a negotiable instrument image, the negotiable instrument image in a first digital image format; convert the negotiable instrument image from the first digital image format to a second digital image format; dynamically determine a maximum pixel count threshold by sampling multiple areas in the converted negotiable instrument image; count a number of a type of pixels in a signature window of the converted negotiable instrument image to generate a signature window pixel count, wherein the type of pixels comprise dark pixels; compare the signature window pixel count to the maximum pixel count threshold; and determine a potential signature error when the signature window pixel count is greater than the maximum pixel count threshold. - View Dependent Claims (11, 12)
