Where is the real value of the image at location , and is the voxel value of the image at the same coordinate. The and values correspond to the maximum and minimum real values, which may also be a function the location, although at a reduced dimensionality. The values of and are global to the volume and do not vary with position.
For more information on these scaling values, see the functions:
int miget_volume_valid_range(mihandle_t volume, double *valid_max, double *valid_min); int miget_slice_range(mihandle_t volume, const unsigned long location, double *slice_max, double *slice_min);
