Lung cancer nodules, particularly adenocarcinoma, contain a complex intermixing of cellular tissue types: incorporating cancer cells, fibroblastic stromal tissue, and inactive fibrosis. Quantitative proportions and distributions of the various tissue types may be insightful for understanding lung cancer growth, classification, and prognostic factors.(More)
For successful cure, cancer has to be detected as early as possible. Since cancer starts from a single cell, this can best be done using cytopathological methods. One important diagnostically relevant measure is the proliferation rate of the cells, which can be estimated from segmented silver stained nuclei. However, the microscopy images of silver stained(More)

Immunocytochemical markers are increasingly applied for diagnosis of diseases. Usually two or more marker stains are applied at once, together with a counterstain for a reliable microscopic investigation of cell specimens. As a preprocessing step for the detection of marker-positive cells, other stains should be removed by image processing techniques. This(More)
