Texture Analysis to Trophoblast and Villi Detection in Placenta Histological Images

摘要

The paper presents two methods of an automatic tropho-blasts and villi detection in histological images to support the pathomorphological diagnostic procedure. The studied slides represent the placenta villi from spontaneous miscarriage stained with the Hematoxylin and Eosin. The proposed methods are based on texture analyses, as Local Binary Pattern and Unser, and mathematical morphology operations. The research on placenta villi detection and the evaluation on the histological images is needed to support clinical studies. The results of the automatic trophoblasts and villi detection were compared with the expert’s annotations. The average coverage of the detected trophoblast areas is 93.65% for the Unser- method and 77.06% for the LBP method. The obtained results confirm efficiency of the proposed solutions.
