Area-granulometry: an improved estimator of sizedistribution of image objects
K.N.R. Mohana Rao, Andrew Graham Dempster · Electronics Letters · 2001
The most commonly used morphological procedure for estimating size distribution of image components is the granulometry proposed by Matheron. Sometimes this method requires some a priori knowledge of image component shape and fails to produce satisfactory results on certain images when the image components are non-flat. A new method (using morphological area-open) is proposed which is simple, more straightforward and the size distribution obtained is more informative.
