How to characterize particles with image analysis?

Particles can be characterized using various related particle shape parameters, such as:

• Area-equivalent diameter
• Perimeter-equivalent diameter
• Circularity
• Ellipse ratio
• Aspect ratio
• Compactness
• Box ratio
• Straightness
• Martin diameter
• Convexity
• Concavity
• Irregularity

They are vital parameters that are beneficial to the evaluation of sample quality and scientific research.

For more details about the above-mentioned particle shape parameters, please refer to A guide to particle size and shape parameters by image analysis
