Image and Visual Representation Lab

Best Technical Paper award at SIGGRAPH 2022

Published:18.07.22 — The paper "CLIPasso: Semantically-Aware Object Sketching" by Yael Vinker, Ehsan Pajouheshgar, Jessica Y. Bo, Roman Bachmann, Amit Haim Bermano, Daniel Cohen-Or, Amir Zamir and Ariel Shamir received the Best Technical Paper award at SIGGRAPH 2022. Ehsan is a PhD student of IVRL since 2021. Our work converts an image of an object to a sketch, allowing for varying levels of abstraction, while preserving its key visual features. Even with a very minimal representation (the rightmost flamingo and horse are drawn with only a few strokes), one can recognize both the semantics and the structure of the subject depicted.

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/
