Image_AveragePixelInterpolation Class Reference

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)
.
