Convolutional Neural Network on Semi-Regular Triangulated Meshes and its Application to Brain Image Data
Caoqiang Liu, Hui Ji, Anqi Qiu
We developed a convolution neural network (CNN) on semi-regular triangulated meshes whose vertices have 6 neighbours. The key blocks of the proposed CNN, including convolution and…
