Stefan, I concur. Juan, 0.9 might have been a more plausible value, since
if I'm not mistaken it is "number of pixels in image / number of pixels in
the convex hull". Convex hull image will have more number of pixels. ;)
Couple of things:
1. This error seems to pop up for this specific case. In the sense, if
you remove the 1 in the 1st row, `regionprops` computes the 'Solidity'
perfectly. No need of padding as well.
2. The error comes up for all the three 'ConvexImage', 'ConvexArea' and
'Solidity' even with the padded image. Whereas, `convex_hull_image`
computes it alright. So, specifically for this padded case there seems to
be a problem with the way the array is being passed and not Delaunay.
First, I think we need to find why the dual nature, `convex_hull_image`
independently works fine but not from `regionprops`. Next and a probable
way forward would be try/except, if an error occurs, then pad the image and
again try/except.
What do you'll think?
