Deep Learning

The evolution of deep learning has been led by applications in computer vision, image processing, computer graphics, and computational photography such as object detection and recognition, image restoration, and image synthesis and manipulation. In our lab, we study deep learning such as new neural network architectures, and training strategies for improving the performance of such applications.

One paper accepted to ICCV 2017

One paper of ours titled “Convergence Analysis of MAP based Blur Kernel Estimation” has been accepted to International Conference on Computer Vision (ICCV) 2017! ICCV is one of the most prestigious conferences in computer vision, and will be held in Venice, Italy from October 22 to 29, 2017.

KCGS 2017 Best Paper Award

Our paper “Deep Learning based Photo Horizon Correction”, which was published in the Journal of the Korea Computer Graphics Society, was awarded the Best Paper Award at the annual conference of Korea Computer Graphics Society. The conference was held in Jeju, Korea from July 12 to 14, 2017.
