Abstract

The slice-adaptive histogramming method for improving coarse segmentation of structures from volume data (especially extraction of anatomical structures in the lower torso from computerized tomography data) is introduced. The method uses a series of local histograms to enable a final segmentation that can adapt to slice-to-slice intensity variations.
