Banknote Image Processing Device Pseudo-Damage Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Obtaining a large number of damaged banknote images requires significant effort and workload by physically damaging real banknotes, which is inefficient and potentially harmful.
Innovation Solution
A banknote image processing device that uses a processor to perform pseudo-damage processing on normal banknote images, simulating damages such as holes, cuts, tears, folds, stains, and washing, generating damaged banknote images without physically altering real banknotes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If physical damage processing is performed on real banknotes to obtain damaged banknote images, then a large number of damaged banknote images can be obtained, but the workload and effort required become excessive
Solution Approach 1:
The patent applies the copying principle by creating synthetic damaged banknote images through image processing techniques rather than physically damaging real banknotes. The system uses normal banknote images and applies virtual damage effects (holes, cuts, tears, folds, stains, washing) through software algorithms, thereby obtaining numerous damaged banknote images without the high workload of physical processing.
2Quantity of substance
If physical damage processing is performed on real banknotes, then damaged banknote images can be obtained, but the process becomes complex and time-consuming
Solution Approach 1:
The patent replaces the mechanical system of physical damage processing with an information processing system. Instead of physically damaging banknotes using mechanical means, the system uses image processing algorithms to virtually apply damage effects, significantly reducing processing time and eliminating the complexity of physical handling and damage application.
3Adaptability or versatility
If real banknotes are physically damaged to create training data, then diverse damaged banknote images can be obtained, but the process is potentially harmful to the banknotes
Solution Approach 1:
The patent uses the copying principle by creating virtual copies of damaged banknote images through image processing rather than physically damaging the original banknotes. The system applies various damage types (holes, cuts, tears, folds, stains, washing) through software algorithms on normal banknote images, achieving diverse damaged banknote images without causing any physical harm to the actual banknotes.
