Ref-Segmentation for multi-object. Only get one object.

[steven22tom]

I tried using Referring segment for “person wear helmet” to detect all people wearing helmet in an image.
But I only get one detection result.（The correct number of results is four）
Could it be an issue with the referring expression, that it only returns one result?

Referring segmentation is usually applied to a single object (one text match only one target in Refcoco).
You can use the open-seg mode for multiple objects using prompts like "Segment all person." or "Segment helmet.' The combination maybe not be well supported owing to data distribution but you can try it.

run_and_show("Open-Set Segmentation", 
             "Segment all objects in this image.", 
             "assets/6.jpg", 
             seg_mode='openseg')
