Abstract: A method of automatic segmentation of a maxillofacial bone in a CT image using a deep learning, the method includes receiving input CT slices of the CT image including the maxillofacial bone, segmenting the input CT slices into a mandible and a portion of the maxillofacial bone excluding the mandible using a convolutional neural network structure and accumulating 2D segmentation results which are outputs of the convolutional neural network structure to reconstruct a 3D segmentation result. The convolutional neural network structure includes an encoder including a first operation and a second operation different from the first operation in a same layer and a decoder including a third operation and a fourth operation different from the third operation in a same layer.
