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.
