Image Based View Synthesis
… by a set of un-calibrated images from different viewpoints. After automatically recovering the geometric transformations between these images, a series of photo-realistic virtual views can be rendered and a virtual environment covered by these several static cameras can be synthesized. This …

View Synthesis for Visuomotor Policy Learning
… framework that equips visuomotor policies with a view synthesizer. This generative model has the ability to envision novel viewpoints and perspectives of the 3D environment. Unlike training a visuomotor policy solely on real-world data, a view synthesizer can produce coherent views of a 3D scene …

Novel View Synthesis from Casually Recorded Videos
Generating new, photorealistic views of a scene given only a single video is a difficult task that computer vision researchers have worked on for decades. This problem has recently seen a resurgence in interest due to its potential application in areas such as virtual reality. However, current …

View synthesis for kinetic depth X-ray imaging
… the development and analysis of feature based synthesis of transmission X-ray images. The synthetic imagery is formed through matching and morphing or warping line-scan format images produced by a novel multi-view X-ray machine. In this way video type sequences, which periodically alternate …

A Novel Inpainting Framework for Virtual View Synthesis
Multi-view imaging has stimulated significant research to enhance the user experience of free viewpoint video, allowing interactive navigation between views and the freedom to select a desired view to watch. This usually involves transmitting both textural and depth information captured from …

Generalizable and Efficient Novel View Synthesis with Perceptual Foundations
Recent advancements in novel view synthesis have demonstrated remarkable potential. Although these methods are capable of generating visually compelling novel views, their reliance on per-scene retraining severely limits their scalability and practical applications. The central goal of this …

View synthesis for depth from motion 3D x-ray imaging.
… checkpoints. The technique requires multiple views of the luggage to be obtained from an arrangement of linear X-ray detector arrays. This research investigated a solution to the unique problems defined when considering the possibility of replacing some of the X-ray sensor views with synthetic …

Learning to handle occlusion for motion analysis and view synthesis
… example, when we see a car gradually blocks our view of a human figure, we know that either the car or the human is moving. We also know that the human behind the car will be visible again if we move to other positions. As many vision-based intelligent systems need to handle and react to visual …

Vision-Based Rendering: Using Computational Stereo to Actualize IBR View Synthesis
… omnidirectional images to synthesize novel views. We encapsulate our contributions into a working system that we call Vision-Based Rendering (VBR). With our VBR system we are able to automatically create simulation content from a large unordered collection of input photographs. However, …

Hardware Acceleration for Real-Time Compression of 3D Gaussians
… Splatting (3DGS) is a technique for novel view synthesis, where images of a scene from a specific viewpoint are generated using images from different viewpoints, that has gained popularity for its reduced computational overhead, resulting in faster training and rendering times compared to …

Mesh Differentiable Rendering for Real-World Scenes
… effective tool for 3D reconstruction and novel view synthesis. Most state-of-the-art differentiable rendering methods use purpose-built renderers to optimize specialized, nonstandard 3D representations. However, most downstream applications of differentiable rendering rely on 3D meshes, which …

Shape, Reflectance, and Illumination From Appearance
… graphics applications such as relighting, view synthesis, and object capture (as desired in extended reality [XR], etc.). In this dissertation, we study inverse rendering by recovering three-dimensional (3D) shape, reflectance, illumination, or everything jointly under different setups. The …

Editing Conditional Radiance Fields
… (NeRF) is a scene model supporting high-quality view synthesis, optimized per scene. In this thesis, we explore enabling user editing of a category-level NeRF – also known as a conditional radiance field – trained on a shape category. Specifically, we introduce a method for propagating coarse 2D …
