  1. 基于内容的医学图像检索简介

  2. 基于内容的影像检索：CBIR (Content-based Image Retrieval) 基于内容的影像检索是由机器自动提取图像特征，包括颜色，形状，纹理等，对数据库中图像和样本图像在特征空间进行相匹配，检索出与样本相似的图像的过程。 图像检索演示系统

  3. 某些存在的系统 • Photobook, MIT • face, texture and shape database • WebSeek, Columbia U • WWW image search engine • include more than 650,000 images • ImageRover, Boston U • WWW image search engine • use 32 robots to collect one million images monthly • VideoBook, HKUST • video retrieval system • QBIC, IBM • commercial system (trademark) • MARS, Illinois • image retrieval with relevance feedback mechanism • VideoClip, Columbia U • video parsing and editing • Princeton University • high-level video representation • NeTra, UCSB • object-based video representation

  4. 病例资源 库 数据库 影像库 影像 特征 提取 检索 程序 特征提取 特征库 显示

  5. 效果 ？ 图像分割！

  6. 从腹部CT图像中提取肝脏 从肝脏图像中提取病变部位 提取病变部位的特征（灰度，形状，纹理等） 确定最优特征向量组 机器学习，模式识别

  7. 所需知识 数字图像处理 数据库 C语言/ Matlab 解剖学常识 医学影像诊断学
