1) Why Image Analysis Method?


  • Easy
    Capture an image of particles, identify particles, then measure their size and shape. Every step of image analysis is easy and clear.


  • Shape analysis
    Based on a direct view of particles, it is possible to analyze not only the size of particles, but also their shape. 


  • Seeing is believing
    The image analysis method determines the size and shape of every individual particle and then sums it up to form a statistic. Details of particle size or shape distribution can be accurately provided.


2) Why Static Image Analysis Method?


  • Clear vision
    In static image analyzers, precision microscopes and high-resolution cameras are specialized for high - quality particle images. 


  • Undersized particle sensitivity
    The static image analysis method is sensitive to undersized particles; it is even possible to estimate the size of undersized particles.


  • Small sample volume
    The static image analysis method requires a small volume of samples. A few drops of emulsions or a few micrograms of powders are enough to do a measurement.


3) Particle Size and Shape Parameters:


  • Size parameters
    Equivalent diameters: area-equivalent diameter、perimeter-equivalent diameter; Feret diameters: maximum and minimum Feret diameters,  XLF ("length") 
    Martin diameters: maximum and minimum Martin diameters; Legendre ellipse: major and minor axes


BeVision S1 Size parameters


  • Shape parameters
    Size difference in 2 directions: aspect ratio、L/W ratio、ellipse ratio; Round-likeness and rectangle-likeness: Circularity、irregularity、compactness、extent、box ratio
    Contour concavity: Concavity、convexity、solidity; For elongated particles: Elongation、straightness
