Portrait shadow manipulation

X Zhang, JT Barron, YT Tsai, R Pandey… - ACM Transactions on …, 2020 - dl.acm.org
Casually-taken portrait photographs often suffer from unflattering lighting and shadowing
because of suboptimal conditions in the environment. Aesthetic qualities such as the …

Editing soft shadows in a digital photograph

A Mohan, J Tumblin… - IEEE Computer Graphics …, 2007 - ieeexplore.ieee.org
In this article, we develop tools for shadow modification in images where a shadowed region
is characterized by soft boundaries with varying sharpness along the shadow edges …

Learning to remove soft shadows

M Gryka, M Terry, GJ Brostow - ACM Transactions on Graphics (TOG), 2015 - dl.acm.org
Manipulated images lose believability if the user's edits fail to account for shadows. We
propose a method that makes removal and editing of soft shadows easy. Soft shadows are …

LightPainter: interactive portrait relighting with freehand scribble

Y Mei, H Zhang, X Zhang, J Zhang… - Proceedings of the …, 2023 - openaccess.thecvf.com
Recent portrait relighting methods have achieved realistic results of portrait lighting effects
given a desired lighting representation such as an environment map. However, these …

Face relighting with geometrically consistent shadows

A Hou, M Sarkis, N Bi, Y Tong… - Proceedings of the IEEE …, 2022 - openaccess.thecvf.com
Most face relighting methods are able to handle diffuse shadows, but struggle to handle
hard shadows, such as those cast by the nose. Methods that propose techniques for …

Texture-consistent shadow removal

F Liu, M Gleicher - Computer Vision–ECCV 2008: 10th European …, 2008 - Springer
This paper presents an approach to shadow removal that preserves texture consistency
between the original shadow and lit area. Illumination reduction in the shadow area not only …

Chromatic shadows for improved perception

V Šoltészová, D Patel, I Viola - Proceedings of the ACM SIGGRAPH …, 2011 - dl.acm.org
Soft shadows are effective depth and shape cues. However, traditional shadowing
algorithms decrease the luminance in shadow areas. The features in shadow become dark …

Gaussian shadow casting for neural characters

L Bolanos, SY Su, H Rhodin - Proceedings of the IEEE/CVF …, 2024 - openaccess.thecvf.com
Neural character models can now reconstruct detailed geometry and texture from video but
they lack explicit shadows and shading leading to artifacts when generating novel views and …

Portrait eyeglasses and shadow removal by leveraging 3d synthetic data

J Lyu, Z Wang, F Xu - … of the IEEE/CVF Conference on …, 2022 - openaccess.thecvf.com
In portraits, eyeglasses may occlude facial regions and generate cast shadows on faces,
which degrades the performance of many techniques like face verification and expression …

Ssn: Soft shadow network for image compositing

Y Sheng, J Zhang, B Benes - Proceedings of the IEEE/CVF …, 2021 - openaccess.thecvf.com
We introduce an interactive Soft Shadow Network (SSN) to generates controllable soft
shadows for image compositing. SSN takes a 2D object mask as input and thus is agnostic …
