Image Thresholding by Indicator Kriging
July 1999 (vol. 21 no. 7)
pp. 590-602

Abstract—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 $\Pi_0$, a second fraction to $\Pi_1$, 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.
