Seed growing algorithm to find voxels in a three-dimensional array according to their correlation to a seed voxel. The correlation is measured according to the fourth dimension of the array.

img |
is the four-dimensional array of medical imaging data. |
x,y,z |
are the coordinates of the seed voxel. |
thresh |
is the minimum correlation for inclusion in the region. |
Correlation coefficients are computed for every voxel in the input array. A recursive algorithm is then used to grow the region of interest (ROI) from the seed voxel in three dimensions. All adjacent voxels, where the correlation exceeds the threshold, are included.
