The research of content-based BCTIIS

The diagnostic value of CT (computed tomography) checking for encephalic illness is affirmative. How to prevent the man-made error and improve the interpret level for brain CT images, is the purpose of this paper. Under a prototype of brain-CT-images-interpret system (BCTIIS), we discuss the intelligent content-based image retrieval techniques. In this paper, for image retrieving, we not only issued the transform of content-based retrieval languages, but also developed a weighted complex similarity query algorithm (WK-NN) for optimum query efficiency.
