Evaluation of Interpolation Effects on Upsampling and Accuracy of Cost Functions-Based Optimized Automatic Image Registration
Figure 8
Reference with resolution (top row), downsampled by a factor of 2 in the direction with resolution (middle row), interpolated by trilinear (bottom row), axial view (left column), sagittal (middle column), and coronal view (right column). The yellow arrows in sagittal and coronal views show significant jagged-edge distortion.
