摘要 基于内容的多媒体信息检索在图像检索中意义重大,其检索的依据主要是多媒体的特征向量值,因此多媒体信息特别是图像的特征向量的组织直接影响到数据检索的效率。对基于内容的多媒体检索技术进行了研究,同时借鉴基于关键字的检索技术,引进了二叉排序树来组织图像的特征向量,利用成熟的二叉排序树算法进行特征向量值的检索,提高了图像检索的效率。 Content-based multimedia retrieval Technology is very import image retrieval technology, but the multimedia information construction limited the rate ofthe multimedia information retrieval. The multimedia retrieval technology is studied, retrievaltechnology based on keywords is refered, then an search tree is given to construct the multimedia eigenvector, which improves the rate of the information retrieval.
