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 a plurality of images, reserving at least one image as a target image, and using a remaining portion of the plurality of images as atlas images in a multi-atlas segmentation; provide at least one set of labels per atlas image within an image space of the atlas image; register the atlas images to the target image by way of computed transformations; propagate the sets of labels from the image spaces of the atlas images to an image space of the target image using the computed transformations to generate a propagated label map; and create a segmented target image by way of label fusion using intensity data of the target image and the propagated label map.
