The study aims to develop an intelligent system to detect discrete surface defects in rail infrastructure using vision technology.
Developed a visual detection system focusing on image enhancement and automatic thresholding techniques.
Introduced a local Michelson-like contrast measure for improving rail image quality.
Implemented a new proportion emphasized maximum entropy thresholding algorithm for effective defect detection.
Achieved a recall of 91.61% for Type-II defects and 88.53% for Type-I defects.
Demonstrated that the MLC image enhancement method significantly improves defect-background distinction.
Showed the PEME thresholding algorithm outperforms established methods in defect recognition.
