Abstract
Transmittance spectra of fungi were estimated
from seven-band optical micrographs. An optical
microscope adjusted with a single-chip CCD
camera with seven band filters was used for
image acquisition. The Wiener method was
applied to estimate the transmittance spectra
of five species that belong to one genus
of fungi. The Wiener estimation operator
was calculated from transmittance spectra
of 16 color transparencies and the corresponding
camera responses. The estimated transmittance
spectra were used for segmentation of conidia
and hyphae in fungal optical micrographs;
then the competitive learning in an artificial
neural network was applied to the segmentation.
