摘要
图像是教学资源建设中的重要组成部分。借鉴元数据标准建设中的概念，针对基于内容意义上的图像，定义了图像元数据。在图像特征提取上应用了基于内容的视觉信息检索技术，在图像表示上借鉴了元数据标准建设中的描述规范，描述语言和描述方法。通过实验，分别对图像从颜色和纹理两个方面进行检索，并给出检索结果及对检索结果的分析。
The image is crucial part of construction of educational resource. The definition of image metadata is referred from the concept of metadata standard construction and mainly based on content of images. In the aspect of images feature extraction, the technique of content-based visual information retrieval is usually implemented, in terms of image defined, it is referred from description specification, language and method of construction of metadata standard.
