Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional template matching techniques are too slow and expensive for low-cost, high-volume applications, such as real-time print quality control, due to factors like poor image quality, occlusion, and non-rigid transformations, making them cost- and time-prohibitive.
Innovation Solution
An enhanced fuzzy template-matching scheme using capacitive or frequency-coupling of damped oscillators with active circuits, implemented with thin-film transistors, which allows for faster and more cost-effective template matching by arranging damped oscillators in a two-dimensional matrix and utilizing peripheral circuitry for accuracy assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional algorithmic template matching techniques are used, then matching accuracy is improved, but processing speed and cost deteriorate
Solution Approach 1:
The patent replaces conventional algorithmic/template-based matching with a physics-based resonant oscillator system. Instead of using computational algorithms to compare patterns, the invention uses mechanical resonant oscillators where pattern matching emerges from physical resonance phenomena. This substitution of mechanical/physical systems for computational algorithms enables real-time processing while maintaining matching accuracy.
Solution Approach 2:
The invention changes the fundamental parameter space from digital/computational to physical/oscillatory. By transforming the matching problem into a domain governed by resonant frequency parameters and oscillatory behavior, the system achieves both high accuracy through resonance matching and high speed through parallel physical evolution of oscillators, avoiding sequential computational processing.
2Measurement precision
If conventional algorithmic template matching techniques are used, then matching accuracy is improved, but manufacturing cost deteriorates
Solution Approach 1:
The patent replaces expensive computational hardware and algorithm processing with a physics-based oscillator array that performs matching through natural resonant phenomena. This mechanical/physical approach eliminates the need for high-performance computing resources, reducing manufacturing costs while maintaining accuracy through physical resonance principles.
Solution Approach 2:
The resonant oscillator system performs pattern matching autonomously through self-organizing physical phenomena. The oscillators naturally synchronize or desynchronize based on pattern similarity without requiring external computational control, reducing the need for complex control systems and lowering overall manufacturing cost.
3Reliability
If real-time image processing is performed on poor quality images, then detection capability is improved, but processing complexity and time deteriorate
Solution Approach 1:
The patent replaces time-consuming digital image processing with parallel physical oscillation evolution. Multiple oscillators process pattern information simultaneously through their natural resonant behavior, achieving real-time detection even from poor quality images without sequential computational processing delays.
Solution Approach 2:
The system performs preliminary pattern encoding into oscillator initial conditions or parameters before the actual matching process. This preliminary preparation allows the oscillators to immediately begin resonant matching when presented with input images, reducing processing time while maintaining detection capability through pre-configured resonant relationships.
