A system for automatic quantification of morphological changes of cell lines, proposed for cytotoxicity tests of biomaterials, is presented. Light-micrographs of cultured cells are segmented by adaptive thresholding within a local adaptive window. Connected cells in binarized micrographs are separated by a novel morphological multiscale method, treating(More)
Cytotoxicity tests are important for the screening and evaluation of biocompatibility of artificial organs. Morphologic changes of cells that were contacted biomaterials or biomaterial extracts indicate their toxicity. However, information on cytotoxic effects is still obtained by subjective visual inspection of microscopic samples. In this article, a novel(More)
