Abstract
Computer image processing techniques are often used in, for example,
the analysis of thin sections of reservoir rock because of the large
amounts of data contained in a single digitized section image. Erosion
and dilation are operations frequently used in this type of work to
iteratively smooth the pore perimeters and in estimating pore radii, volume,
and roughness. Because of the size of each image, erosion and dilation of
pore complex images is a time consuming process. A recent method called
\fIglobal\fR erosion is much faster whether used on small, in-memory
images or large images residing on a file. Use of this method should allow
processing of larger images, or a greater number of small images, than do
the standard methods.
