描述
polar_trans_image_invpolar_trans_image_invPolarTransImageInvPolarTransImageInvPolarTransImageInvpolar_trans_image_inv transforms the polar coordinate
representation of an image, stored in PolarImagePolarImagePolarImagePolarImagepolarImagepolar_image, back onto
an annular arc in Cartesian coordinates, described by the radii
RadiusStartRadiusStartRadiusStartRadiusStartradiusStartradius_start and RadiusEndRadiusEndRadiusEndRadiusEndradiusEndradius_end and the angles
AngleStartAngleStartAngleStartAngleStartangleStartangle_start and AngleEndAngleEndAngleEndAngleEndangleEndangle_end with the center point
located at (RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn). All of these values can
be chosen as real numbers. The overall size of the target image
will be WidthWidthWidthWidthwidthwidth x HeightHeightHeightHeightheightheight pixels.
The parameter InterpolationInterpolationInterpolationInterpolationinterpolationinterpolation is used to select the
interpolation method 'bilinear'"bilinear""bilinear""bilinear""bilinear""bilinear" or
'nearest_neighbor'"nearest_neighbor""nearest_neighbor""nearest_neighbor""nearest_neighbor""nearest_neighbor". With 'nearest_neighbor'"nearest_neighbor""nearest_neighbor""nearest_neighbor""nearest_neighbor""nearest_neighbor", the
gray value of a pixel in the output image is determined by the gray
value of the closest pixel in the input image. With
'bilinear'"bilinear""bilinear""bilinear""bilinear""bilinear", the gray value of a pixel in the output image
is determined by bilinear interpolation of the gray values of the
four closest pixels in the input image. The mode
'bilinear'"bilinear""bilinear""bilinear""bilinear""bilinear" results in images of better quality, but is
slower than the mode 'nearest_neighbor'"nearest_neighbor""nearest_neighbor""nearest_neighbor""nearest_neighbor""nearest_neighbor".
The angles and radii are inclusive, which means that the first row
of the input image will be mapped onto a circle with a distance of
RadiusStartRadiusStartRadiusStartRadiusStartradiusStartradius_start pixels from the specified center and the last
row will be mapped onto a circle of radius RadiusEndRadiusEndRadiusEndRadiusEndradiusEndradius_end。

polar_trans_image_invpolar_trans_image_invPolarTransImageInvPolarTransImageInvPolarTransImageInvpolar_trans_image_inv can be executed on an OpenCL device. There can
be slight differences in the output compared to the execution on the CPU.
Additionally, for images of type 'byte'"byte""byte""byte""byte""byte", 'int2'"int2""int2""int2""int2""int2" or
'uint2'"uint2""uint2""uint2""uint2""uint2" the system parameter 'int_zooming'"int_zooming""int_zooming""int_zooming""int_zooming""int_zooming" selects between
fast calculation in fixed point arithmetics
('int_zooming'"int_zooming""int_zooming""int_zooming""int_zooming""int_zooming" = 'true'"true""true""true""true""true")
and highly accurate calculation in floating point arithmetics
('int_zooming'"int_zooming""int_zooming""int_zooming""int_zooming""int_zooming" = 'false'"false""false""false""false""false"). Fixed point calculation
can lead to minor gray value deviations. In this case, the
domain of resulting images can differ as well.
