A General Pipeline for Dense Illuminant Estimation via Physically Based Synthetic Data
Luca Cogo, Gianmarco Corti, Simone Bianco +1
Illuminant estimation is a fundamental problem in computational photography, as it enables the correction of color shifts induced by varying lighting conditions. While learning-bas…
Illuminant-Adaptive 3D Lookup Tables for Camera Color Correction
Claudio Rota, Luca Cogo, Simone Bianco +1
Color correction is a key component of camera image signal processing (ISP) pipelines, encompassing illuminant discounting and colorimetric mapping of device-dependent sensor respo…
Face anonymization preserving facial expressions and photometric realism
Luigi Celona, Simone Bianco, Raimondo Schettini
The widespread sharing of face images on social media platforms and in large-scale datasets raises pressing privacy concerns, as biometric identifiers can be exploited without cons…
Leveraging Multispectral Sensors for Color Correction in Mobile Cameras
Luca Cogo, Marco Buzzelli, Simone Bianco +2
Recent advances in snapshot multispectral (MS) imaging have enabled compact, low-cost spectral sensors for consumer and mobile devices. By capturing richer spectral information tha…
