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
