AI Technical Summary
Technical Problem
Conventional crack-detection methods for illuminated electronic device screens are prone to high false-positive indications, making them inefficient and inconsistent in identifying cracks accurately.
Method used
A method involving image subtraction of illuminated and unlighted images, followed by image pyramid generation and kernel convolution to identify cracks at various angles, with secondary checks to validate crack detection, reduces false positives.
Benefits of technology
The method effectively detects cracks in illuminated screens with high accuracy by minimizing false positives, ensuring reliable crack identification.
