    • Methods and computer-readable media for propagating content category information to images stored in a database are described. A seed image that is associated with a known content category is received. A content-based image retrieval is conducted using the seed image as a search query image. A number of search result images are identified. The content category is propagated to the search result images. Metadata associated with the search result images is aggregated and analyzed to identify domains that should also be associated with the content category. Additional images that are associated with the domain are identified and the content category propagated thereto. The process is iterated using the additional images as search query images for the content-based image retrieval.
    • 描述用于将内容分类信息传播到存储在数据库中的图像的方法和计算机可读介质。 接收与已知内容类别相关联的种子图像。 使用种子图像作为搜索查询图像进行基于内容的图像检索。 识别出多个搜索结果图像。 内容类别被传播到搜索结果图像。 与搜索结果图像相关联的元数据被聚合和分析,以识别也应该与内容类别相关联的域。 识别与域相关联的附加图像,并将内容类别传播到其上。 使用附加图像作为用于基于内容的图像检索的搜索查询图像来迭代该过程。
