Digital Optics: Some Remarks on the Accuracy of Particle Image Analysis
Michael Schäfer · Particle & Particle Systems Characterization · 2002
The article has the aim to investigate some typical errors which arise in digital images of particles, and where it is possible, tries to assess the effective inaccuracies in the determination of distributions of size, length, perimeter and shape. In the second chapter, the errors typical for very low pixel numbers are discussed, in the third chapter, resolution independent errors in the determination of length and perimeter are investigated. In the last chapter, the consequences for shape determination are summarised.
