How to segment the Gundam in image? Any suggestion?

[garrisonz]

Thanks for your great work!

SAM cannot segment out Gundam, please refer to the below example image and the all_mask image.
I hope segment mask fill full the Gundam region, howerer SAM leave a large black region on Gundam which means no mask.
Any suggestion? Thanks!

input image

all_mask. (Black region on Gundam means no mask)

How about the automatic mask mode?
Any suggestion if I want the automatic mask including Gundam region.
