WebIn many image analysis methods for particle measurement, each particle is recorded only once in random orientation. Especially for particles with a defined geometry, such as lenses or rods (e.g.: extrudates), it is very likely that the relevant projection is not captured during the acquisition: for example, rods tend to be measured "too short" with random orientation.
