Diameter of the largest circle that can be inscribed inside an area.

The object is transformed into a binary image. A distance transform is applied on the binary image which calculates the largest distance to the outline of the object or any holes the object contains. Extracting the point with the largest distance yields the maximum inscribed circle. The diameter is twice the largest distance.

Size limitation: If the object width or height exceeds 20000 pixel, the feature calculation does not work and returns no result.

• Unit: pixel
