Description
In histopathological diagnosis, a clinical pathologist
discriminates between normal tissues and cancerous tissues.
However, recently, the shortage of clinical pathologists is
posing increasing burdens on meeting the demands for such
diagnoses, and this is becoming a serious social problem.
Currently, it is necessary to develop new medical
technologies to help reduce these burdens. Therefore, as a
diagnostic support technology, this project proposes an
extended method of higher-order local autocorrelation
(HLAC) feature extraction for classification of
histopathological images into normal and anomaly. The
proposed method can automatically classify cancerous
images as anomaly by using extended geometric invariant
HLAC features with rotation- and reflection-invariant
properties from three-level histopathological images, which
are segmented into nucleus, cytoplasm and background. In
conducted experiments, we demonstrate a reduction in the
rate of not only false-negative errors but also of false-
positive errors, where a normal image is falsely classified as
an image with an anomaly that is suspected as being
cancerous.
