Video compression patent and licensing

Published:05.07.21 — We released an online demo of our extreme video completion method. Our technology is very energy and time-efficient on the encoder side (we require practically 0 computation and no specialized hardware like typical DCT-based encoders), it can reach extreme compression rates with complete rate flexibility and can achieve better visual reconstruction at these rates compared with the MPEG-4 H264 standard. This makes it ideal for instance for video-transmitting IoT devices, surveillance cameras, drone transmission, or emergency deployment transmission where bandwidth is very limited. Users can visualize different results and test with their own videos too on: adefan.epfl.ch For the more technically curious readers, we have an associated publication in the leading signal processing conference IEEE ICASSP that can be accessed here: https://infoscience.epfl.ch/record/277003/

Depth-guided image relighting NTIRE workshop at CVPR

Published:05.07.21 — IVRL members Majed El Helou and Ruofan Zhou co-organised this workshop, using the VIDIT dataset with geometry information. You can access the challenge paper here. 250 participants registered from various research labs, companies, and universities internationally. 

We released the image relighting dataset "VIDIT"

Published:04.07.21 — We released depth information for our image relighting dataset VIDIT. It is used for the NTIRE workshop competitions in CVPR 2021 Image relighting is fundamental for domain adaptation (data augmentation, normalization), photo montage and photo manipulation for aesthetics.
