MICR Code Line Resolution Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The finance industry faces challenges in efficiently processing high volumes of check images due to the lack of a reliable method to determine the imaging resolution of imaged documents, as this information is often not recorded or recorded incorrectly, hindering the use of image processing technologies like OCR.
Innovation Solution
A system and method that extracts the magnetic ink code recognition (MICR) code line from a document image, calculates coordinate values for MICR characters, and uses statistical analysis to determine a representative resolution value, allowing for accurate determination of image resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If image processing technologies like OCR are used to process check images, then processing capability is improved, but the lack of reliable resolution information prevents accurate processing
Solution Approach 1:
The system uses the MICR code line itself to determine the resolution of the image. The MICR characters serve as a self-contained reference standard that automatically provides the resolution information needed for processing, without requiring external resolution data or manual intervention.
Solution Approach 2:
The system changes the approach to resolution determination by using the known physical dimensions of MICR characters as a reference parameter. By measuring the pixel dimensions of MICR characters and comparing them to their standard physical size, the system calculates the resolution and uses this calculated value for subsequent processing operations.
2Ease of manufacture
If imaging resolution is not recorded or is recorded incorrectly in the image header, then image capture is simplified, but accurate image processing cannot be performed
Solution Approach 1:
The MICR code line acts as an intermediary reference element. Instead of relying on potentially incorrect metadata in the image header, the system uses the MICR characters as a physical reference standard that mediates between the captured image and the required resolution information, allowing accurate measurement regardless of header accuracy.
Solution Approach 2:
The system replaces the reliance on metadata (software-based resolution storage) with a physical measurement approach using MICR characters. By measuring the pixel dimensions of the MICR characters and using their known physical dimensions, the system substitutes indirect metadata reliance with direct physical measurement.
3Measurement precision
If resolution determination methods are developed to enable image processing, then processing accuracy is improved, but system complexity increases
Solution Approach 1:
The system extracts the resolution determination function from the general image processing workflow and integrates it specifically into the MICR code line analysis. By focusing the resolution measurement on the MICR characters alone, the system isolates the measurement task and uses the known dimensions of these characters to directly calculate resolution without complex multi-step analysis.
