The user interface for segmentation in Amira. In the volume rendering view, we can observe that two neurons are in proximity and have complex details. However it is difficult to tell them apart or infer their shapes from any of the slice views. Unfortunately, users have to select structures from the slice views rather than the volume rendering view, where they can actually see the data more clearly. Many interactive volume segmentation tools in neurobiology use similar interactions, which are difficult to use for complex shapes.
