class PlanarPixelInterpolation from Image inherits PixelInterpolation from Image
|
|
|
|
---Purpose: 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 .
