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…
Removing out-of-focus blur from a single image
Guodong Xu, Chaoqiang Liu, Hui Ji
Reproducing an all-in-focus image from an image with defocus regions is of practical value in many applications, eg, digital photography, and robotics. Using the output of some exi…
Weighted total variation based convex clustering
Guodong Xu, Yu Xia, Hui Ji
Data clustering is a fundamental problem with a wide range of applications. Standard methods, eg the -means method, usually require solving a non-convex optimization problem. Re…
Coherence retrieval using trace regularization
Chenglong Bao, George Barbastathis, Hui Ji +2
The mutual intensity and its equivalent phase-space representations quantify an optical field's state of coherence and are important tools in the study of light propagation and dyn…
