1. A non-transitory computer readable storage medium for segmenting an image using a processor, the non-transitory computer readable storage medium including instructions to command the processor to: obtain one or more target images; obtain one or more propagated label probabilities for the one or more target images; segment the one or more target images using a cost function of a deformable atlas model; and identify segmented structures within the one or more target images based on the segmented one or more target images; wherein the deformable atlas model utilizes structure boundary information to take local minimum intensities at edges along a structure contour; wherein the instructions command the processor to use the following to segment the one or more images: π ( t + 1 ) = arg ⁢ max π ⁢ ∑ j ⁢ ⁢ ∑ k ⁢ ⁢ w jk ( t ) ⁢ log ⁢ ⁢ π jk + log ⁢ ⁢ f ⁡ ( π | I ) wherein log f (π|I) is a deformable atlas model term.
