Static Public Member Functions

static vtkMatrix4x4 * RegisterFiducialSets (SignFiducialCollection *set1, SignFiducialCollection *set2)
 Performs SVD-based registration for two fiducial sets.
static float abs (float)
 Computes the absolute value of a number.
static float dist (int a[2], int b[2])
 Computes the distance between two points in 2 dimensions.
static float dist (float a[3], float b[3])
 Computes the distance between two points in 3 dimensions.
static void Normalize (float *v)
 Normalizes a vector.
static void MultiplyMatrix (const double **A, const double **B, unsigned int rowA, unsigned int colA, unsigned int rowB, unsigned int colB, double **C)
static double ** AllocateMatrix (int r, int c)
static int ComputeRasToIjkFromCorners (double *ftl, double *ftr, double *fbr, double *ltl, double zoffset, vtkImageData *image, vtkMatrix4x4 *posMat)
 Computes the RAS to IJK matrix based on the corners of the image. The strategy here is as follows. We create a 4x4 matrix called Ras, which has in its columns the homogeneous RAS coordinates of four corners of the data volume. We then create another matrix called Ijk, which has in its columns the IJK coordinates of those same four corners. We then solve for RasToIjk in the equation RasToIjk*Ras=Ijk.
static void ComputeRasToIjkFromScanOrder (const char *order, vtkImageData *image, vtkMatrix4x4 *posMat)
 Computes the RAS to IJK matrix based on the scan order.
