The class AveragePixelInterpolation is used to compute a SubPixel
value on non integer Image coordinate
AveragePixelInterpolation redefined a new method to compute a
SubPixel value .
SubPixel value is the average of the three nearest Pixel in
the Image .
If V1, V2, V3, V4 is the value of the three nearest Image
Pixel V = ( V1+V2+V3 ) / 3 is the Image SubPixel value
on non integer coordinate (FX,FY)

Redefined the method to compute SubPixel's value on non integer Image coordinate. LowerX,LowerY,UpperX,UpperY is the Image Min Max, it's use check if the SubPixel coordinate FX,FY is outside of image. Return True if Interpolation Succes. Return False if the SubPixel is out from Image. | |
