Sparse-view Material Decomposition for Spectral X-ray CT using Neural Radiance Fields

e-Journal of Nondestructive Testing
Photon-counting X-ray detectors, in contrast to conventional flat panel detectors, have the capability of distinguishing between photons with different energies, and have been leveraged for material decomposition tasks for materials with similar X-ray ...

MS-NeRF: Multi-Space Neural Radiance Fields

IEEE Transactions on Pattern Analysis and Machine Intelligence
Existing Neural Radiance Fields (NeRF) methods suffer from the existence of reflective objects, often resulting in blurry or distorted rendering. Instead of calculating a single radiance field, we propose a multi-space neural radiance field (MS-NeRF) that represents the scene using a group of feature fields in parallel sub-spaces, which leads to a ...

NeRF-Texture: Synthesizing Neural Radiance Field Textures

IEEE Transactions on Pattern Analysis and Machine Intelligence
Texture synthesis is a fundamental problem in computer graphics that would benefit various applications. Existing methods are effective in handling 2D image textures. In contrast, many real-world textures contain meso-structure in the 3D geometry space, such as grass, leaves, and fabrics, which cannot be effectively modeled using only 2D image textures.

Interactive geometry editing of Neural Radiance Fields

Displays
In this paper, we propose a method that enables interactive geometry editing for neural radiance fields manipulation. We use two proxy cages(inner cage and outer cage) to edit a scene. The inner cage defines the operation target, and the outer cage defines the adjustment space. Various operations apply to the two cages. After cage selection, operations
