plane_deviation — Calculate the deviation of the gray values from the approximating
plane_deviation calculates the deviation of
the gray values in
Image from the approximation of the
gray values through a plane. Contrary to the standard deviation in
intensity slanted gray value planes also
receive the value zero. The gray value plane is calculated
If F is the area of the region, , ,
and the parameters of the
image plane, and (r',c') the center of the region,
Note that the operator
plane_deviation only considers
Regions and ignores any previously set domain
of the input image
It should be noted that the calculation of
not follow the usual definition. It is defined to return the value
0.0 for an image with only one pixel.
Regions, of which the plane deviation is to be calculated.
→object (byte / cyclic)
Gray value image.
Deviation of the gray values within a region.
If F is the area of the region the runtime complexity amounts to O(F).
plane_deviation returns the value 2 (H_MSG_TRUE) if
Image is of the type 'byte'. The behavior in
case of empty input (no input images available) is set via the operator
the behavior in case of empty region is set via
If necessary an exception is raised.
