Hi all,

I have a bunch of pictures like this one:

(A picture of rocks with soil between them)

I would like to detect and extract every single rock in the picture.
What would be the best way to do this? I have tried using Canny edge
detection to find each rock, but even though the contrast between rock
and soil is quite high, I don't get all the edges in the picture.

Also I would like to find the green box which is somewhere at the
center of the picture. How would you suggest that I do that?

Best regards,
Bjarne

When I click the thumbnail, the new web page doesn't respond.
"waiting for" in status bar continues for minutes. You should use
PBase.

You should find the green box by color detection.
