Image and Visual Representation Lab

Welcome to IVRL

The Image and Visual Representation Lab (IVRL) performs research that is primarily focused on the capture, analysis, and reproduction of color images. Aiming to improve everyone’s photographic experience, we develop algorithms and systems that help us understand, process, and measure images.

Our research areas are computational photography, color image processing, computer vision, and image quality.

Best Technical Paper award at SIGGRAPH 2022

— 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.
