Extracting Speech Bubble/Ballon and Panel

[DRL]

Hi there,
I am a new member who just joins today. Perhaps somebody can help me please. I would like to automatically extract speech baloon/bubble and panel of a comic book. Example is given below. What would be the best technique in GIMP to do this please. Any help would be appreciated. Thank you.

You eyes and hand. Hard to automate without extreme AI to "recognize" the bubble.

This said, not very difficult to recreate with a path (and likely faster).
