# Image_PlanarPixelInterpolation Class Reference

The class PlanarPixelInterpolation is used to compute a
SubPixelvalue on non integer Image coordinate
PlanarPixelInterpolation redefined a new method to compute a
SubPixel value .
To compute the value of a Image SubPixel, first we look
for the three nearest Image Pixels .
Then we compute the plane definition in the 3D space
composed by the Image Pixel coordinate and Pixel value
on Z axis .
The SubPixel value is the Z value of ( FX,FY ) point in the
three nearest Image Pixel defined plane .
.
