Evaluation of Interpolation Effects on Upsampling and Accuracy of Cost Functions-Based Optimized Automatic Image Registration
Table 6
The joint entropy for the registered images of matrix size of 256 × 256 × 120 using interpolations of trilinear, B-spline 3rd order, B-spline 4th order, cubic Lagrange, quintic Lagrange, heptic Lagrange, windowed Sinc, and cost functions of CR, LS, NCC, and NMI. Their entropies were achieved using mutual information.
