Bilinear Interpolation / Double Interpolation



Linear Interpolation

Adicot, Inc's Bilinear Interpolation / Double Interpolation Calculator uses values at the four nearest grid points to calculate an interpolated value for a point within the grid. The interpolated value is obtained by constructing a linear function along each of the two directions perpendicular to the grid axes and then using these two functions to estimate the value at the desired point. Bilinear interpolation is particularly useful for resampling images and other two-dimensional data. It can estimate the values of pixels or data points at non-grid locations. It is a relatively simple and computationally efficient method that can produce accurate results in many applications.
