In-Depth Information
Table 6.2:
Experimental results produced by mapping MRI brain image 2 into
images 1, 3, 4, and 5 (see Fig. 6.7). The thin-plate spline algorithms compared
in this table are the unidirectional landmark (UL-TPS), consistent landmark
(CL-TPS), consistent intensity (CI-TPS), and consistent landmark and intensity
(CLI-TPS) algorithms. The statistics computed for these experiments were the
average landmark error (ALE) in pixels, maximum landmark error (MLE),
maximum inverse error (MIE) in pixels, average inverse error (AIE) in pixels,
masked average intensity difference (MAID), minimum Jacobian value (MJ),
inverse of the maximum Jacobian value (IJ) and the Jacobian error (JE)
