Title of meeting: Mathematical Morphology
All welcome - attendance free
Speaker: ILYA MOLCHANOV (University of Glasgow)
Title of paper: How to average a cat and a dog?
Synopsis: The main aim of the talk is to explain various
elementary techniques that involve random sets and can be used to
handle samples of images. A particular emphasis is placed
on averaging of samples of images, binarisation
of grey-scale images and digitalisation of images.
Speaker: STEPHEN MARSHALL (University of Strathclyde)
NEAL HARVEY (Los Alamos National Research Labs)
Title of paper: Film archive restoration using spatio temporal
soft morphological filters
Synopsis: his talk will describe how soft morphological filters
may be trained to remove film dirt whilst preserving structure
with image sequences. Soft morphological filters combine the
properties of set theoretic operators (traditional morphology)
and rank ordering to produce operators with slightly relaxed
constraints i.e. soft structuring elements. The soft morphological
filters are applied over a spatio-temporal region of support
and the optimum filtering sequence, structuring element and rank
(softness) parameter are determined by iterative search techniques
using genetic algorithms. A small area of the data set is chosen
for training the filters subject to a mean absolute error
criterion. An example of the technique applied to an old film
sequence will be demonstrated as part of the talk.
Speaker: GRAHAM HORGAN (Biomathematics and Statistics Scotland)
Title of paper: Some morphological studies of soil structure
Synopsis: The structure of soil material, pores and cracks and of the
living material that grows in it is complex, and has
important effects on the properties of the soil. Some applications
of morphological tools to study this structure will be described.
