ATM Document Noise Removal via Neural Network Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image analysis and processing technologies are inefficient and unreliable in detecting and removing noise artifacts from images, often mistakenly removing desired content or failing to remove noise artifacts entirely.
Innovation Solution
A system trained on clean and noisy images extracts features to identify noise artifacts, using a neural network dropout layer to filter out noise artifact features, and adapts its processing based on the device's capability to efficiently remove noise from images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current image analysis and processing technologies are used to remove noise artifacts, then processing speed may be maintained, but reliability deteriorates due to mistaken removal of desired content or failure to remove noise artifacts
Solution Approach 1:
The image processing system is segmented into multiple specialized modules: a noise artifact detection module that identifies noise characteristics, a decision module that determines whether to remove detected artifacts, and a removal module that executes the removal. This segmentation allows each module to specialize in one aspect of the problem, improving overall reliability while maintaining manageable complexity through modular design.
Solution Approach 2:
An intermediary decision-making layer is introduced between noise detection and noise removal. This intermediary module analyzes detected noise artifacts and determines whether they should be removed or preserved, preventing mistaken removal of desired content. The intermediary acts as a mediator that balances noise removal with content preservation, significantly improving reliability.
2Reliability
If advanced noise removal algorithms are implemented, then reliability improves, but processing time increases
Solution Approach 1:
The system applies partial action by selectively removing only those noise artifacts that meet specific removal criteria, rather than attempting to remove all detected noise. This approach maintains high reliability for cases requiring removal while reducing processing time by skipping artifacts that don't meet removal thresholds or can be handled by simpler methods.
Solution Approach 2:
The system incorporates self-service through adaptive learning where the intermediary module learns from previous decisions and outcomes. By automatically adjusting its decision-making based on feedback, the system improves its efficiency over time, reducing processing time while maintaining or improving reliability without requiring constant manual intervention or reconfiguration.
3Measurement precision
If comprehensive feature extraction is performed to accurately identify noise artifacts, then measurement precision improves, but processing complexity increases
Solution Approach 1:
The feature extraction process applies local quality by extracting different types of features at different stages and locations. The detection module extracts basic noise characteristics, while the intermediary module extracts more sophisticated features only when needed for difficult decisions. This localized application of comprehensive feature extraction maintains high precision for critical cases while reducing overall processing complexity.
Data Source
AI summary
An Automated Teller Machine (ATM) for detecting security vulnerabilities by removing noise artifacts from documents receives a transaction request when a document is inserted into the ATM, where the document contains a noise artifact at least partially obstructing a portion of the document. The ATM generates an image of the document, where the image displays at least one data item comprising a sender's name, a receiver's name, and a number representing an amount. The ATM determines whether the noise artifact obstructs at least partially one data item. In response to determining that the noise artifact obstructs at least partially one data item, the ATM generates a test clean image of the document by removing the noise artifact from the image. In response to determining that the noise artifact is removed, the ATM approves the transaction request.
