Wykrywanie krwi na obrazach bronchoskopowych za pomocą sieci neuronowych
(Wydawnictwa AGH, 2009) Mikrut, Zbigniew; Duplaga, Mariusz
In the paper the experiments with using SOM-supervised neural networks for pixel (HSV) classification were presented. Six visually different images were chosen to be the basis for the SOM training. For these images learning sets were created based on the refined masks of the bleeding regions pointed out by the doctor. Next the six learning sets were merged and the ambiguous pixel representations were removed. Two types of SOM-supervised networks (of »normal« and »small« sizes) were created and learned. The classification results were obtained and analyzed both for learning sets and for 14 test images. Several conclusions were stated concerning the learning methodology and the bleeding areas postprocessing.
