Three-dimensional Display via Multi-layer Translucencies
Tiancheng Sun, Huarong Gu
We built a display system using light field display and pyramid-like mirror. The displayed allows the observer to see the virtual 3D objects from different directions in the air.

SIGGRAPH blog post
We proposed a new BRDF gamut mapping algorithm using two-step optimization. We optimize the luminance with the guide of perceptual attributes in the first step, and optimize the ink coefficients using image comparison in the second step.
Revisiting Cross-channel Information Transfer for Chromatic Aberration Correction
Tiancheng Sun, Yifan (Evan) Peng, Wolfgang Heidrich
The IEEE International Conference on Computer Vision (ICCV), 2017, pp. 3248-3256
By modelling the similarity between different channels, we propose a new blind image deconvolution algorithm which transfers information from clear channel to blurry ones, and yield better results than state-of-the-art methods in both refractive and diffractive optical systems.
Convolution Neural Networks with Two Pathways for Image Style Recognition
Tiancheng Sun, Yulong Wang, Jian Yang, and Xiaolin Hu
IEEE Transactions on Image Processing (Volume: 26, Issue: 9, Sept. 2017)
We add the ideas used in image style transfer into traditional CNN network for image style recognition, and achieve state-of-the-art results on three benchmark datasets.
