Numerous scientific and research centres are searching for solutions concerning the problem of quality classification of animal oocytes. Conducting such studies is purposeful, particularly in the context of constant attempts to improve the quality of food products, which depends on the breeding value of livestock. Therefore, searching for methods of stimulation of proper development of a larger number of animal oocytes, particularly in extracorporeal conditions, gains special importance. An increasing interest in assisted reproduction techniques resulted in searching for new, increasingly effective methods of quality assessment of mammalian gametes and embryos. The expected progress in the production of animal embryos in vitro is largely dependent on proper classification of obtained oocytes. The aim of this work was to develop a non-invasive method for the quality assessment of oocytes, performed on the basis of graphic information encoded in the form of monochromatic digital images obtained via microscopy techniques. The classification process was conducted based on the information presented in the form of microphotography pictures of domestic pig oocytes, using advanced methods of neural image analysis.
