The 8 Pt SinX/X resampling option determines the gray level from the weighted average of the 64 closest pixels to the specified input coordinates and assigns the value to the output coordinates.
The 16 Pt SinX/X resampling option determines the gray level from the weighted average of the 256 closest pixels to the specified input coordinates and assigns the value to the output coordinates.
The resulting image from using either of these methods is sharper than one produced by Bilinear Interpolation, and it does not have the disjointed appearance produced by Nearest Neighbor Interpolation. However, since the gray level values are altered by these methods, image classification processes should be performed before the interpolation.
