EBTM: An Enumeration-Based Thresholding Method for Degraded Circular Dot Segmentation

Area of Science:

• Computer Vision
• Image Processing
• Pattern Recognition

Background:

• Circular dots are vital for measurement applications due to symmetry and scalability.
• Degradation from noise, low contrast, or damage complicates accurate circular dot extraction.
• Existing methods struggle with segmented circular dots in challenging image conditions.

Purpose of the Study:

• To introduce a novel enumeration-based thresholding method (EBTM) for robust circular dot segmentation.
• To address the limitations of traditional thresholding techniques in degraded images.
• To improve the accuracy and reliability of circular dot extraction in measurement applications.

Main Methods:

• An enumeration-based thresholding scheme generates multiple candidate segmentation outputs.
• A developed assessment criterion evaluates the quality of each candidate output.
• Optimal segments are selected and combined to achieve the final segmentation result.

Main Results:

• The EBTM method demonstrates superior performance in segmenting degraded circular dots.
• The approach shows enhanced robustness against common image degradation factors.
• Comparative studies confirm the effectiveness of the EBTM over traditional methods.

Conclusions:

• The proposed EBTM offers a more reliable solution for circular dot segmentation in challenging environments.
• This method advances image processing techniques for measurement applications.
• EBTM provides a robust alternative for extracting features from degraded circular dot patterns.
