Title StatementImproved classification of noisy microscopic images by a neural network with principal component projections as inputs by Maricor Narvaez Soriano
Physical Description86 leaves figures, graphs, tables
Summary, Etc.The error propagation in a trained sigmoid-activated neural network with a principal components preprocessors (PCAN+NN is derived and is shown to be smaller than that of a trained neural network without a preprocessor (NN). Both networks are tested to identify graylevel 10x10 pixel images of methaphase spreads, unburst cells and empty slides corrupted with additive and multiplicative Gaussian noise, impulse noise, constant gain and additive and multiplicative Gaussian noise with gain. Results indicate that a PCAN+NN is indeed more robust than a NN in classifying noisy images. It is also shown that reconstruction of a noisy image using a small number of principal components improves image quality
