Rays as Pixels: Learning A Joint Distribution of Videos and Camera Trajectories
arXiv:2604.09429v4 Announce Type: replace Abstract: Recovering camera parameters from images and rendering scenes from novel viewpoints have been treated as separate tasks in computer vision and graphics. This separation breaks down when image coverage is sparse or poses are ambiguous, since each task depends on what the other produces.
Foveated-Imaging Geometry CT Architecture and Seeded Diffusion Model Enabling Global Super-Resolution Reconstruction
Announce Type: new Abstract: For X-ray computed tomography (CT), a smaller detector pixel size generally leads to higher scanner spatial resolution, but inevitably increases system cost as well as data overhead in acquisition and processing. To achieve high-resolution (HR) CT imaging in a more resource-efficient manner, we propose a Foveated-Imaging Geometry CT (FIGCT) architecture, which integrates local HR data into an acquisition scheme dominated by low-resolution (LR) measurements. We...
Space telescopes are now overwhelmed by satellite trails
Space telescopes are now overwhelmed by satellite trails Lisa Lock Scientific Editor Andrew Zinin Lead Editor Unfortunately, there's more bad news to report on the clear skies front. A new paper, available on the arXiv preprint server from researchers at NASA's Ames Research Center, reports that 73.3% of images the agency's new SPHEREx space telescope collected between May and September of last year were contaminated by at least one artificial satellite trail. And it's only going to get...
Voxel Space
Let us go back to the year 1992. The CPUs were 1000 times slower than today and the acceleration via a GPU was unknown or unaffordable. 3D games were calculated exclusively on the CPU and the rendering engine rendered filled polygons with a single color.
Recent application studies of an INTPIX4NA SOIPIX detector-based X-ray camera using an SiTCP-XG 10GbE-based high-speed readout system at KEK facilities
arXiv:2603.09461v3 Announce Type: replace Abstract: The Silicon-On-Insulator PIXel (SOIPIX) detector is a unique monolithic structure imaging device currently being developed by the SOIPIX group, led by the High Energy Accelerator Research Organization (KEK). Our detector team at the KEK Photon Factory (PF) has developed an X-ray camera based on the INTPIX4NA SOIPIX detector. This detector provides a sensitive area of 14.1 $\times$ 8.7 $\mathrm{mm^2}$, with 425,984 pixels arranged in an...
X-ray Response of the Fully-Depleted, p-Channel SiSeRO-CCD
Announce Type: replace Abstract: We present an X-ray characterization of a fully depleted, 725 $\mu$m thick p-channel SiSeRO-CCD. Measurements with a $^{55}$Fe source yield an energy resolution of $54 \pm 0.9$ eV ($14.6 \pm 0.25 e^{-}$) at 5.9 keV for single-pixel events, indicating that the SiSeRO amplifier preserves the intrinsic charge resolution of the CCD under multi-sample non-destructive readout. Characterization with a $^{241}$Am source extends the response to higher-energy photons,...
VolFill: Single-View Amodal 3D Scene Reconstruction with Volumetric Flow Matching
arXiv:2605.31466v1 Announce Type: new Abstract: Reconstructing the complete geometry of a scene from a single RGB image remains challenging - especially when inferring hidden structures where visual evidence is incomplete. We introduce VolFill, a generative framework that predicts the 3D structure of the complete scene rather than relying on traditional pixel-aligned regression. Our method utilizes a hybrid 3D VAE to compress sparse truncated unsigned distance function grids into a compact...
Guided progressive reconstructive imaging: a new quantization-based framework for low-dose, high-throughput and real-time analytical ptychography
Announce Type: replace Abstract: By profiting from recent developments in detector technologies, making it possible to access a stream of detection events with few-ns time resolutions, a new ptychographic workflow is established. This methodological framework, referred to as guided progressive reconstructive imaging, relies on a quantization-based description of the acquired intensity, through an elementary derivation. Established direct phase retrieval solutions, such as the Wigner...
The 11 best cozy sci-fi games for those chill cosmic vibes
The 11 best cozy sci-fi games for those chill cosmic vibes From farming and walking sims to space trucking, you can live that cozy life… but in space! The best sci-fi games are often pigeonholed into specific genres like shooters, strategy games, and RPGs, and for good reason; franchises like Mass Effect, StarCraft, and Half-Life are all-time classics. But sometimes it’s nice to explore the stars in a safer way... a more chill, vibey kind of way that helps you relax and unwind.
