Amazing Content. Clearly Explained !!!

Hi Umar, thanks for this amazing code explanation. Just one question, how is the prediction_iou computed in the Automatic Mask generation of SAM? I am asking because we only have the model's prediction and to compute iou you need ground truth labels. Thanks!

[Maximos]

incredible explanation! would you be interested in reviewing the SEEM (Segment Everything Everywhere All at Once) model?

[Alice-yqyy]

How does SAM calculate the predicted IoU for our output masks, if it doesn't have a ground truth for the given image?

[wklusmy]

thanks a lot. how can we access to codes that explained in video?

[Esra]

One question regarding the Vision Transfomrer, even if this is not the main topic:
Why do they use the FIRST Token? Wouldn't usually the LAST token caputre all the information of the before seen ones?

[missmiir]

Is there any way we can mask same object with same colors ?

[syedabdul]

A video for coding SAM from scratch would be entertaining!

[urkfwfl]

Nice video!
I think your understanding of the source code is really good.
Could you please share your annotated code? It will be very helpful for my undergraduate graduation project.

based on python roadmap, what topic should i focused to sir?
