I am working on a project to analyze a screen printing processing. The samples have extreme contrast variations. The goal is a consistent color across the printed area and identifying the defect locations. I am using particle analysis with limited success. The key to particle analysis is setting the threshold correctly that can be done manually. I have tired correcting images for brightness and using a histogram to detect the transition from darker particles to lighter. All have yielded limited success. Is there a better way? Sorry, can't post BMP files.
