Cross-Camera Deep Colorization

Yaping Zhao, Haitian Zheng, Mengqi Ji +1

In this paper, we consider the color-plus-mono dual-camera system and propose an end-to-end convolutional neural network to align and fuse images from it in an efficient and cost-e…

EFENet: Reference-based Video Super-Resolution with Enhanced Flow Estimation

Yaping Zhao, Mengqi Ji, Ruqi Huang +2

In this paper, we consider the problem of reference-based video super-resolution(RefVSR), i.e., how to utilize a high-resolution (HR) reference frame to super-resolve a low-resolut…

Zoom in to the details of human-centric videos

Guanghan Li, Yaping Zhao, Mengqi Ji +2

Presenting high-resolution (HR) human appearance is always critical for the human-centric videos. However, current imagery equipment can hardly capture HR details all the time. Exi…

SurfaceNet+: An End-to-end 3D Neural Network for Very Sparse Multi-view Stereopsis

Mengqi Ji, Jinzhi Zhang, Qionghai Dai +1

Multi-view stereopsis (MVS) tries to recover the 3D model from 2D images. As the observations become sparser, the significant 3D information loss makes the MVS problem more challen…

SPI-Optimizer: an integral-Separated PI Controller for Stochastic Optimization

Dan Wang, Mengqi Ji, Yong Wang +2

To overcome the oscillation problem in the classical momentum-based optimizer, recent work associates it with the proportional-integral (PI) controller, and artificially adds D ter…

RegNet: Learning the Optimization of Direct Image-to-Image Pose Registration

Lei Han, Mengqi Ji, Lu Fang +1

Direct image-to-image alignment that relies on the optimization of photometric error metrics suffers from limited convergence range and sensitivity to lighting conditions. Deep lea…
