Description The operator gen_image_surface_second_order gen_image_surface_second_order GenImageSurfaceSecondOrder GenImageSurfaceSecondOrder GenImageSurfaceSecondOrder gen_image_surface_second_order
creates a curved
gray value surface according to the following equation:
The size of the image is determined by Width Width Width Width width width
and Height Height Height Height height height
.
The parameters Row Row Row Row row row
and Column Column Column Column column column
define the reference point
of the created gray surface. If fit_surface_second_order fit_surface_second_order FitSurfaceSecondOrder FitSurfaceSecondOrder FitSurfaceSecondOrder fit_surface_second_order
was used to
determine the parameters of the gray surface, this reference point should
correspond to the center of gravity that is used in the surface equation
(see fit_surface_second_order fit_surface_second_order FitSurfaceSecondOrder FitSurfaceSecondOrder FitSurfaceSecondOrder fit_surface_second_order
). Its coordinates can be computed as
follows:
intersection(ROI, Image, RegionIntersection) intersection(ROI, Image, RegionIntersection) Intersection(ROI, Image, RegionIntersection) Intersection(ROI, Image, RegionIntersection) Intersection(ROI, Image, RegionIntersection) intersection(ROI, Image, RegionIntersection)

The gray values are of the type Type Type Type Type type type
(see gen_image_const gen_image_const GenImageConst GenImageConst GenImageConst gen_image_const
for a detailed description of the pixel types).
Gray values outside the valid area are clipped.
