Android Question Comic book panel edge detection

Hi!

Having seen that there are a few OpenCV / EdgeDetection libraries around, I would like to ask their creators/users if it's possible to accomplish the task of auto detecting comic book / manga panels.

Note 1: It should also work for grayscale and line-art (black and white) input sources.

Note 2: There are non-standard panel shapes like triangles, trapezoids and circles.

Note 3: If someone proposes a custom solution, I will gladly pay for it (as much as I can afford).

Just seen it (not very active here lately). Not sure if still interested, but shouldn't be too difficult with OpenCV if the background behind the panels is a solid color :)

Yes I am! :)

Indeed, the background is usually either solid black or white. There are some odd shapes every now and then though, also "panel-in-panel", which might be trickier handle.
I was wondering if OpenCV by itself would be enough or if perhaps, this is more of a job for a Neural Network...

I've never used the OpenCV lib before, by the way. How's the learning curve?
