Foreseeing Reconstruction Quality of Gradient Inversion: An Optimization Perspective
HyeongGwon Hong, Yooshin Cho, Hanbyel Cho +2
Gradient inversion attacks can leak data privacy when clients share weight updates with the server in federated learning (FL). Existing studies mainly use L2 or cosine distance as…
Generative Approach for Probabilistic Human Mesh Recovery using Diffusion Models
Hanbyel Cho, Junmo Kim
This work focuses on the problem of reconstructing a 3D human body mesh from a given 2D image. Despite the inherent ambiguity of the task of human mesh recovery, most existing work…
Implicit 3D Human Mesh Recovery using Consistency with Pose and Shape from Unseen-view
Hanbyel Cho, Yooshin Cho, Jaesung Ahn +1
From an image of a person, we can easily infer the natural 3D pose and shape of the person even if ambiguity exists. This is because we have a mental model that allows us to imagin…
Localization using Multi-Focal Spatial Attention for Masked Face Recognition
Yooshin Cho, Hanbyel Cho, Hyeong Gwon Hong +4
Since the beginning of world-wide COVID-19 pandemic, facial masks have been recommended to limit the spread of the disease. However, these masks hide certain facial attributes. Hen…
