Differentiable Direct Volume Rendering [PDF]

IEEE Transactions on Visualization and Computer Graphics, 2022
We present a differentiable volume rendering solution that provides differentiability of all continuous parameters of the volume rendering process. This differentiable renderer is used to steer the parameters towards a setting with an optimal solution of a problem-specific objective function.

Real-Time Volume-Rendering Image Denoising Based on Spatiotemporal Weighted Kernel Prediction [PDF]

Journal of Imaging
Volumetric Path Tracing (VPT) based on Monte Carlo (MC) sampling often requires numerous samples for high-quality images, but real-time applications limit samples to maintain interaction rates, leading to significant noise.

Topology-Controlled Volume Rendering [PDF]

IEEE Transactions on Visualization and Computer Graphics, 2007
Topology provides a foundation for the development of mathematically sound tools for processing and exploration of scalar fields. Existing topology-based methods can be used to identify interesting features in volumetric data sets, to find seed sets for accelerated isosurface extraction, or to treat individual connected components as distinct entities ...

Optimization of Breast Tomosynthesis Visualization through 3D Volume Rendering [PDF]

Journal of Imaging, 2020
3D volume rendering may represent a complementary option in the visualization of Digital Breast Tomosynthesis (DBT) examinations by providing an understanding of the underlying data at once. Rendering parameters directly influence the quality of rendered

Global illumination rendering versus volume rendering for the forensic evaluation of stab wounds using computed tomography [PDF]

Scientific Reports, 2022
We compared three-dimensional (3D) CT images of stabbing victims subjected to volume-rendering (VR) or global illumination-rendering (GIR), a new technique now available for the reconstruction of 3D CT images.

Homomorphic-Encrypted Volume Rendering [PDF]

IEEE Transactions on Visualization and Computer Graphics, 2021
Computationally demanding tasks are typically calculated in dedicated data centers, and real-time visualizations also follow this trend. Some rendering tasks, however, require the highest level of confidentiality so that no other party, besides the owner, can read or see the sensitive data.
