Meaning of CUBIC CONVOLUTION in English


it is similar to bilinear interpolation except the weighted average is calculated from the 16, not 4, nearest input cell centers and their values.

Note: Bilinear interpolation or cubic convolution should not be used on categorical data. While all three techniques can be applied to continuous data, with nearest neighbor producing a blocky output, bilinear interpolation producing smoother results, and cubic convolution produing the sharpest results.
