Pixel Resampling Methods• Used in both pyramid creation and display resampling• Interpolates pixel values from original raster valuesForDiscreteData Nearest neighbor• Value of nearest pixel• Does not create new values• Fastest overallForContinuousData Bilinear interpolation• Weighted average of fournearest pixels• Faster than cubic convolution• Smooths most imagery Cubic convolution• Sixteen nearest pixels• Usually most pleasing result• Sharpens most imagery
