英文摘要： Digital pathological diagnosis technology made the doctor's qualitative or semi-quantitative pathology model into a quantitative model of pathological diagnosis based on image processing and recognition, it brought epoch-making reform for pathological diagnosis.The project will combine pathologic diagnosis of hepatocellular carcinoma, which is difficult to be early diagnosis, with the international emerging digital pathology technology, and investigate and develope the key technologies of digital pathology on hepatocellular carcinoma based on whole slide imaging (WSI),This project has important scientific and practical value. Focused on the challenges of digital pathology diagnosis of hepatocellular carcinoma, the project intends to make full use of the multi-disciplinary theory of computing anatomy, digital image processing, machine learning, pattern recognition, pathology, put forward a series of new methods, investigate the segmentation problem of cells and adhesion between cells, the computer representation problem of the growth state and the pimelosis level of liver cells, the quantification problem of HCC pathological characteristics and the selection problem of effective feature, the construction problem of HCC classification model with high generalization ability, and find the differences between normal cells and tumor cells to reveal the potential regularity of cancerization. and construct a high-performance key technologies of digital pathology diagnosis for hepatocellular carcinoma with independent intellectual property rights in our country, and improve the accuracy and efficiency of HCC pathological diagnosis, enrich and develop the theory and method of digital pathologic diagnosis.
