Due to the cardinal motor symptoms in PD, our … WebIn this work, we proposed a fast and robust segmentation of thalamus using convolutional neural networks. First, cropped image which included the thalamus are extracted. Convolutional neural network (CNN) is then trained to segment the whole thalamus region. Intensity constrained model is constructed to obtain the final segmentation.
