Evaluation of Interpolation Effects on Upsampling and Accuracy of Cost Functions-Based Optimized Automatic Image Registration

<table>Joint histogram for registered 3D MRI volumes using an intensity-based cost function (CR (first column), LS (second column), NCC (third column), and NMI (fourth column)) are shown. The top row is generated from the images when registered using windowed Sinc interpolation, and the bottom row is generated from the images when registered using B-spline 3rd-order interpolation.</table>
