The research of semantic content applied to brain CT images

The brain CT image database is the result of the efforts made at the No. 161 Center Hospital for accurately diagnosing encephalic illness. How to prevent the man-made error and improve the interpret level for brain CT images, is the purpose of this database, also for our paper. So the intelligent brain CT image retrieval process become important. In our paper, we discuss four stages in content-based semantic retrieval. Finally, we apply a new complex similarity query algorithm to fulfill the image retrieval.
