Comparison of dendrite and axon classification using AlexNet and a revised model. (a) Axons are discrete, and dendrites are continuous. (b) Both axons and dendrites are continuous. The left segment is extracted from a long axon. The right segment is extracted from a local dendrite. Red color indicates the axon, and blue color indicates the dendrite in (a) and (b). Note that all these 3D segments are manually annotated using Virtual Finger technology [7, 9]; neurite types are automatically annotated by the proposed module
