Methods of operating an image-based check processing system to detect a double feed condition of checks and an apparatus therefor
View Patent ↗A method is provided of operating an image-based check processing system to detect a double feed condition of checks. The method comprises attempting to read a magnetic ink character recognition (MICR) codeline from front of a check item. The method also comprises electronically by a rear imaging camera, capturing image data which is representative of a rear image of the check item as the check item is transported from an upstream end of the document feed path to a downstream end of the document feed path. The method further comprises alerting an operator when information from the attempted read of a MICR codeline from front of the check item and information from the rear image of the check item meet predetermined criteria which is indicative the check item comprising two overlapping checks.
1. A method of operating an image-based check processing system to detect a double feed condition of checks, the method comprising:
reading a magnetic ink character recognition (MICR) codeline from front of a check item;
capturing image data which is representative of an image of the check item as the check item is transported from an upstream end of the document feed path to a downstream end of the document feed path;
electronically by a processor, processing the captured image data to determine if the image of the check item is upside down;
concluding that the check item is a double-fed item when a MICR codeline is readable from the front of the check item and a determination is made that the image of the check item is upside down; and
alerting an operator to indicate a double-fed item when a conclusion is made that the check item is a double-fed item.
2. A method according to claim 1 , wherein capturing image data includes capturing image data which is representative of a rear image of the check item as the check item is transported from the one end of the document transport path to the other end of the document feed path.
3. A method according to claim 1 ,
wherein capturing image data includes capturing image data which is representative of a front image of the check item as the check item is transported from the one end of the document feed path to the other end of the document feed path.
4. A method according to claim 1 , further comprising:
electronically by a processor, processing the captured image data to determine if the image of the check item is upside right and backwards; and
concluding that the check item is a double-fed item when a MICR codeline is readable from front of the check item and a determination is made that the image of the check item is upside right and backwards.
5. A method according to claim 1 , wherein the method is performed by a computer having a memory executing one or more programs of instructions which are tangibly embodied in a program storage medium readable by the computer.
6. A method of operating an image-based check processing system to detect a double feed condition of checks, the method comprising:
reading a magnetic ink character recognition (MICR) codeline from front of a check item;
electronically by a processor, determining a number of check symbols associated with the check item based upon information from the MICR codeline read from the front of the check item;
concluding that the check item is a double-fed item when a determination is made that at least three check symbols are associated with the check item; and
alerting an operator to indicate a double-fed item when a conclusion is made that the check item is a double-fed item.
7. A method according to claim 6 , wherein the check symbol comprises transit Q symbols associated with a check.
8. A method according to claim 6 , wherein the check symbol comprises amount Q symbols associated with a check.
9. A method according to claim 6 , wherein the check symbol comprises account symbols associated with a check.
10. A method according to claim 6 , wherein the method is performed by a computer having a memory executing one or more programs of instructions which are tangibly embodied in a program storage medium readable by the computer.
11. A check processing apparatus comprising:
a document feed mechanism having a document feed path;
a magnetic ink character recognition (MICR) codeline reader arranged to read a MICR codeline from front of a check item as the check item is transported along the document feed path from an upstream end of the document feed path to a downstream end of the document feed path;
a first imaging camera arranged to capture image data which is representative of a front image of a check item as the check item is transported along the document feed path;
a second imaging camera arranged to capture image data which is representative of a rear image of a check item as the check item is transported along the document feed path;
a first optical character recognition (OCR) reader arranged to perform an OCR read of a captured front image of a check item as the check item is transported along the document feed path;
a second OCR reader arranged to perform an OCR read of a captured rear image of a check item as the check item is transported along the document feed path;
a number of pockets located at the downstream end of the document feed path; and
a processor programmed to (i) process data from a MICR codeline read from front of a check item by the MICR reader, (ii) process data from an OCR read of a captured rear image of the check item by the second OCR reader, (iii) control the document feed mechanism to transport the check item to a particular pocket when processed data is indicative of the check item comprising two overlapping checks, (iv) process data from a MICR codeline read from front of the check item by the MICR reader to determine if the check item in the document feed path is a personal type of check, (v) process data from an OCR read of a captured front image of the check item by the first imaging camera to determine if image length is greater than a predetermined length, and (vi) control the document feed mechanism to transport the check item to a particular pocket when the check item is determined to be a personal type check and the image length is determined to be greater than the predetermined length.
12. A check processing apparatus according to claim 11 , wherein the processor is further programmed to (vii) process data from an OCR read of a captured front image of the check item by the first imaging camera to determine a number of check symbols associated with the captured front image of the check item, and (viii) control the document feed mechanism to transport the check item to a particular pocket when the number of check symbols associated with the front image of the check item is at least a predetermined number.
