Title: Analysing differential interference contrast microscope
images: identifying algal cells
Abstract:
This talk will consider an application of digital analysis of
microscope images, namely identifying objects in differential
interference contrast (DIC) microscope images. DIC microscopy is
useful for imaging transparent or near-transparent specimens, but
gives the effect of side illumination. The light and dark edges to
the objects make automatic outline detection difficult. Consideration
of the microscope optics leads to a model for the grey levels in the
image of an object. Results using this in template matching will be
shown for images of yeast cells and algal cells in pond water
samples. Results of some simpler, less computationally intensive,
algorithms will also be shown, and a Bayesian approach considered.
The talk will be followed by tea and biscuits. All those who are
interested are very welcome to attend.
