YOLO-WORLD: Custom Object Detection Without Retraining 

yes, it is similar to that. But this also provides bounding boxes.

I could not figure out a way to do that. I tried to do it using ultralytics but did not work out. You can check my code here: colab.research.google.com/drive/1cxqMiSuNPSwy4z8nhgxIVK8YQxINbak_?usp=sharing

I agree. However, don’t forget that this is the first version of YOLO with such ability. The next versions will be better.
