Some Confusion about annotation #119

Closed ddz16 closed 11 months ago

ddz16 commented 11 months ago

In Thumos14 dataset, there are some confusing annotations. Two action instances with the same action label have temporal overlap. In that case, why not use a single action instance for annotation? For examples, in the "video_validation_0000983," there are two action instances as follows:

           ......
           {
                "label": "VolleyballSpiking",
                "segment": [
                    96.1,
                    97.4
                ],
                "segment(frames)": [
                    2883,
                    2922
                ],
                "label_id": 19
            },
            {
                "label": "VolleyballSpiking",
                "segment": [
                    96.9,
                    97.7
                ],
                "segment(frames)": [
                    2907,
                    2931
                ],
                "label_id": 19
            },
            ......

Why not use a single action instance for annotation, just like:

            {
                "label": "VolleyballSpiking",
                "segment": [
                    96.1,
                    97.7
                ],
            },

I have checked all the videos, and this situation is rare, only appearing in a few videos.
