Cover Story: Recent studies have been evaluating the presence of patterns associated with the occurrence of cancer in different types of tissue. In this article, we describe preliminary results for the automatic detection of cancer (Walker 256 tumor) in laboratory animals using preclinical microphotographs of the subject’s liver tissue. In the proposed approach, two different types of descriptors were explored to capture texture properties from the images, one based on spectral information and another built by application of a granulometry given by a family of morphological filters. We tried three different classifier methods (SVM, kNN, and logistic regression). Promising results were obtained for both descriptors in isolation, and even better results were achieved by combining classifiers based on them. View this paper
