How is bilinear interpolation calculated?
Bilinear interpolation considers the closest 2 × 2 neighborhood of known pixel values surrounding the unknown pixel's computed location. It then takes a weighted average of these 4 pixels to arrive at its final, interpolated value.
How to do bilinear interpolation in Excel?
Name the cell containing the x- and y-values you entered in x and y, respectively. Select the row of x-values in the data table and name those “xvalues”. Select the column of y-values in the same table and name those “yvalues”. Next, select all the air velocity numbers (cells D7-L15) and name them “zvalues”.
