ABSTRACT
<p><b>Abstract</b>—We consider the problem of segmenting a digitized image consisting of two univariate populations. Assume a priori knowledge allows incomplete assignment of voxels in the image, in the sense that a fraction of the voxels can be identified as belonging to population <tmath>$\Pi_0$</tmath>, a second fraction to <tmath>$\Pi_1$</tmath>, and the remaining fraction have no a priori identification. Based upon estimates of the short length scale spatial covariance of the image, we develop a method utilizing indicator kriging to complete the image segmentation.</p>
