Message

“I’m in the Imaging & Sensing project and my mission is to fully maximize image sensor capabilities combining AI technologies. Sony Semiconductor Solutions is the market leader in CMOS image sensor, and they own powerful sensors and sensing technologies. I believe the fusion of AI, sensor and sensing technologies will revolutionize the imaging systems, which can be beyond human perception.”

Publications

UHD-IQA Benchmark Database: Pushing the Boundaries of Blind Photo Quality Assessment

ECCV, 2025
Vlad Hosu, Lorenzo Agnolucci, Oliver Wiedemann, Daisuke Iso, Dietmar Saupe

We introduce a novel Image Quality Assessment (IQA) dataset comprising 6073 UHD-1 (4K) images, annotated at a fixed width of 3840 pixels. Contrary to existing No-Reference (NR) IQA datasets, ours focuses on highly aesthetic photos of high technical quality, filling a gap in …

RAW-Diffusion: RGB-Guided Diffusion Models for High-Fidelity RAW Image Generation

WACV, 2025
Christoph Reinders, Radu Berdan, Beril Besbinar, Junji Otsuka*, Daisuke Iso

Current deep learning approaches in computer vision primarily focus on RGB data sacrificing information. In contrast, RAW images offer richer representation, which is crucial for precise recognition, particularly in challenging conditions like low-light environments. The res…

MocoSFL: enabling cross-client collaborative self-supervised learning

ICLR, 2023
Jingtao Li, Lingjuan Lyu, Daisuke Iso, Chaitali Chakrabarti*, Michael Spranger

Existing collaborative self-supervised learning (SSL) schemes are not suitable for cross-client applications because of their expensive computation and large local data requirements. To address these issues, we propose MocoSFL, a collaborative SSL framework based on Split Fe…
