rectangle detection only detecting large rectangles not smaller ones? iOS, Swift

Question

I am using vision to detect rectangles but it only seems to be detecting larger rectangles that are more square than rectangle. Is there a way to detect longer rectangles?

Answer 1

You have to adjust the minimumAspectRatio of the VNDetectRectanglesRequest which is 0.5 per default. The green rectangle seems to have a much lower one.
