报告摘要：
在一般计算机识别系统里。类别标签仅作为一种区别类与类的标记。而实际上，类别标签也包含了丰富的语义信息。这些语义信息可以被用来帮助识别系统取得更好的性能。本次报告将介绍应用该思路的两个识别系统案例。其中一个用类别标签来提取图像与标签吻合的视觉信息并用来帮助图像搜索。另一个利用类别标签的语义信息来解决视觉关系检测问题。
Abstract
In traditional visual recognition, class labels are merely used as tokens to distinguish different categories. However, in many visual recognition problems, the semantic information beneath the class label can be invaluable for improving the recognition performance. In this talk, I will introduce two of our recent works which leverage semantic information from the class label to guide visual recognition. Specifically, one uses semantic information to extract the visual patterns which are consistent with the class label and uses this scheme for image retrieval. The other uses label semantic information for solving the visual relationship detection problem.
