| Research Abstract |
In this research project, we developed methods for recognizing organs and diseases in medical images based on the generative learning approach, which is robust to the data with large variance such as human organs. In the recognition of the airway and blood vessel trees, we investigated effective image features for the generative learning and extracted them from medical images accurately. In the recognition of organs, we constructed an ATLAS, which represents variations of organs mathematically, and extracted them accurately. In the lymph nodes detection, we developed a novel filter which responses to the lymph nodes specifically, and detected lymph nodes with high accuracy. We confirmed that the generative learning approach was effective for recognition of human organs and diseases.
