摘要
图像相似性度量技术是图像检索中的一个重要问题。为了达到图像检索的目的,需要对图像提取出来的特征进行相似度计算。针对图像内容的不同属性,应采用不同方法计算其相似度,同时采用信息测度概念衡量图像描述的复杂程度,并改进了Shannon概率信息测度方法,用于对检索结果的排序。
The similarity measuring of image is the one key issue in the image retrieval. For the sake of image retrieval, it demands similarity measuring to the characteristic of image. According to different attributes, different similarity measuring methods are applied, at the same time, the information measurement is adopted to scale the complexity of one image＇ s description, and improves the Shannon method to use in the compositor of retrieval outcomes.
