1. A method of processing anatomical structures present in a two-dimensional (2D) image slice using a digital data processor that labels connected components comprising:
(a) selecting a 2D image slice from a plurality of first 2D image slices spanning a three dimensional (3D) volume, using a digital data processing system configured for image processing, where each of the pixels of the selected 2D image slice have one or more of a first intensity value, a second intensity value and a third intensity value, where the second intensity value is greater than the first intensity value, where the third intensity value is greater than the second intensity value;
(b) computing with the digital data processing system a histogram of the 2D image slice;
(c) comparing the histogram with an anatomic atlas of average histograms including computing with the digital data processing system a correlation between the histogram and the anatomic atlas of average histograms;
(d) identifying one or more pixels corresponding with at least two structures of interest in the 2D image slice using the digital data processing system based on the correlation;
(e) assigning with the digital data processing system the one or more pixels identified in step (d) to one or more seed points, where the one or more pixels have an intensity value above the first intensity value or above the second intensity value, where a first seed point corresponds with a first structure of interest, where a second seed point corresponds with a second structure of interest;
(f) growing a region with the digital data processing system from the first seed point to at least one pixel connected to the first seed point until the at least one pixel overruns the second structure of interest to identify the first structure of interest; and
(g) labeling with the digital data processing system the first structure of interest on the selected 2D image slice.
