Splatshot: 3D Face Avatar Generation from a Single Unconstrained Photo
Hao Liang, Zhixuan Ge, Soumendu Majee +3
Reconstructing a photorealistic 3D face avatar from a single unconstrained photograph is challenging: feed-forward 3D Gaussian Splatting (3DGS) models degrade on out-of-distributio…
DRIFT: Deep Restoration, ISP Fusion, and Tone-mapping
Soumendu Majee, Joshua Peter Ebenezer, Abhinau K. Venkataramanan +6
Smartphone cameras have gained immense popularity with the adoption of high-resolution and high-dynamic range imaging. As a result, high-performance camera Image Signal Processors…
FastAvatar: Instant 3D Gaussian Splatting for Faces from Single Unconstrained Poses
Hao Liang, Zhixuan Ge, Soumendu Majee +4
We present FastAvatar, a fast and robust algorithm for single-image 3D face reconstruction using 3D Gaussian Splatting (3DGS). Given a single input image from an arbitrary pose, Fa…
Pixel-weighted Multi-pose Fusion for Metal Artifact Reduction in X-ray Computed Tomography
Diyu Yang, Craig A. J. Kemp, Soumendu Majee +2
X-ray computed tomography (CT) reconstructs the internal morphology of a three dimensional object from a collection of projection images, most commonly using a single rotation axis…
CodEx: A Modular Framework for Joint Temporal De-blurring and Tomographic Reconstruction
Soumendu Majee, Selin Aslan, Doga Gursoy +1
In many computed tomography (CT) imaging applications, it is important to rapidly collect data from an object that is moving or changing with time. Tomographic acquisition is gener…
Multi-Slice Fusion for Sparse-View and Limited-Angle 4D CT Reconstruction
Soumendu Majee, Thilo Balke, Craig A. J. Kemp +2
Inverse problems spanning four or more dimensions such as space, time and other independent parameters have become increasingly important. State-of-the-art 4D reconstruction method…
4D X-Ray CT Reconstruction using Multi-Slice Fusion
Soumendu Majee, Thilo Balke, Craig A. J. Kemp +2
There is an increasing need to reconstruct objects in four or more dimensions corresponding to space, time and other independent parameters. The best 4D reconstruction algorithms u…
