2D Array Interpolation

Filename: 2d_interpolation_demo.zip
Requirements: View

This example demonstrates how to perform a 2D array interpolation by doing two successive 1D interpolations on the rows and columns of the array. It uses a cubic spline interpolant, but can be modified to implement any 1D interpolation method. It can be applied to general 2D arrays or IMAQ images (after using IMAQ ImageToArray).

The demo VI generates a 2D array containing a hyperbolic image and calls the 2Dinterpolation.vi. The generated array and resulting interpolation are displayed in intensity graphs on the front panel.
