摘要
目标检测 、 场景图谱生成 和 region captioning 是在不同语义等级上的图像理解任务它们通常是被绑定在一起的。
本文为了利用跨越不同语义等级的相互联系,本文提出了一种新的神经网络模型,Multi-level Scene Description Network(MSDN).
一种端到端的方式解决这三个联合在一起的问题。
方法简介
对象、文本和regions 首先在一个动态图中表示采用特征细化结构,在三个语义层次上传递消息 在三个基准上测试了本方法。SOTA 3% margin代码地址: Scene Graph Generation from Objects, Phrases and Region Captions

这三个子任务分别代表了图像理解的三个不同的语义水平。
object detection 关注单个对象scene graph 代表不同对象之间的关系region caption 代表一个自由句,用于描述图像
