About OpenV6

[xhonghu]

Why is the number of object classes in the OpenV6 dataset I processed 600, while it is mentioned as 289 object classes in the article? Were there any additional processing steps involved?

OpenImages V6 do have more object categories. However, for the VRD tasks, many categories do not appear in the relationship annotation. For data processing, please check BGNN. I remember that I follow their setting.

非常感谢您能在百忙之中回复我的问题。我阅读了BGNN，论文中提到的目标类为301个，

但它提供的后处理代码和处理过的标注类别好像还是600个。

按照您在data目录中提供的处理代码，我得出来的标注文件目标类为600个。我是不是还漏了哪步没有做呀。

并不是所有600类都有relaitonship annotation的，举个例子，taxi在object detection task里有标注，但是并没有对应的triplet taxi-rel-obj或者sub-rel-taxi。因此就会把这种category滤掉
