Why a majority of segmentation algorithms developed for CAD do not often translate to the clinic: Left column shows two clinical T2 scans. Middle column shows results from our proposed fully automated ensemble technique using several parameter values. Right column shows ITK’s watershed algorithm operating using a fixed set of parameter values initialized to vertebral centers assuming perfect detection of such centers. While the specific set of parameter values chosen works for the image in the top row, it fails for the image in the bottom row. Our technique works for both images.
