, both the acceptable standard error of the volume fraction estimate and the volume fraction of the item of interest determine the total number of points that must be counted (Weibel, 1979).
Subsequently, the quantification of the types of collagens present in the tissue is possible through stereology
. This conventional manual planimetry method has proven its value but it is laborious, and the result depends on the skill of the observer.
of isolated objects with the invariator.
He presents a number of the concepts and principles of the new stereology
to allow readers to design, supervise, and critically evaluate studies.
Let me bring along some details from the history of Acta Stereologica and further of Image Analysis & Stereology

The volume density of the rhabdom was determined from high magnification light micrographs using point-counting stereology
. The average dimensions of the microvilli were determined from electron micrographs and the surface area of membrane per unit volume of microvillar array was then calculated assuming hexagonal close packing of the microvilli.
Whereas the stereology
based on Cavalieri's principle used mostly in vivo studies and in MR images is an unbiased method that may estimate the volume of an object divided into a sequence of parallel cross sectional planes (Gundersen et al., 1988; Roberts et al., 2000).
