Hello,
I was trying to use blob_filter shape squareish to locate retangles in a image but it does not seem to find them. It only seems to find the tall oval. Is there a better way to find retangles?
BTW squareish is listed twice under the shape option. Is there a difference between the two?
Test image
Thank you

- I forgot to negate the image. Is there a difference between the two "squareish" entries.

Good catch on the image negation!
Nope .. the two Squareish attributes are the same and are a typo. The second one has been removed. You can ignore that one.
You might also try the Quadrilateral filters as they also identify squares quite nicely.
STeven.
