Generating detailed 3D models from photographs, that allow for new perspectives on the scene and can even be edited, this is the goal of image-based rendering (IBR), an emerging subfield of computer graphics. In his doctoral thesis, Saarbrücken-based Max Planck researcher Mojtaba Bemana made significant contributions to improving both the practicality and quality of this approach. For this achievement, he has now been awarded one of the prestigious Dissertation Awards by the European Association for Computer Graphics (Eurographics).
In his thesis titled "Efficient Image-Based Rendering", Mojtaba Bemana combines deep learning methods with physically based rendering techniques to make image-based 3D representations more flexible, realistic, and efficient. Unlike traditional 3D computer graphics, where digital representations, especially photorealistic or animated scenes, must be manually created with great time and resource investment, image-based rendering uses photographs as input. AI-based methods such as deep learning then enable the real-time reconstruction of detailed 3D models from these images.

The jury’s official citation states: “In his PhD thesis, Mojtaba Bemana made significant contributions towards image-based rendering. His work offers an efficient solution that enables interactive manipulation of real-world dynamic scenes captured from sparse views, lighting positions, and times, as well as a physically-based approach that facilitates accurate reproduction of the view-dependency effect resulting from the interaction between transparent objects and their surrounding environment. It also proposes a novel visibility metric to identify artefacts in the reconstructed images, and a perception-driven rendering technique providing high-fidelity visual content in virtual reality displays. These innovations contribute to the rapidly developing field of image-based rendering, which has emerged as an alternative and promising approach to directly utilize pre-captured images from the real world to generate realistic images in real-time, avoiding the extensive modeling and expertise required by traditional rendering techniques.”
Mojtaba Bemana received the award in mid-May at the Eurographics Annual Conference in London. The doctoral thesis was written at Saarland University and the Max Planck Institute for Informatics. It was supervised by Prof. Dr. Karol Myszkowski, head of the “HDR Imaging, Perception, and Advanced Displays” group in the Computer Graphics department led by Director Prof. Dr. Hans-Peter Seidel at MPI for Informatics.
