Absolute scaling of small‐ and wide‐angle X‐ray scattering images recorded with short duration X‐ray pulses on a large area fiber‐taper X‐ray detector

Journal of Synchrotron Radiation, EarlyView.
An X‐ray scattering setup designed to capture small‐ and wide‐angle X‐ray scattering on a single, large area detector features a partially transmissive beamstop that facilitates non‐invasive recording of X‐ray beam position and intensity during acquisition of X‐ray scattering images.

A Review of Classical Lossless Data Compression Algorithmsand Their Contemporary Relevance [PDF]

Biuletyn Wojskowej Akademii Technicznej
Compression is data processing aimed at reducing the amount of information (e.g., for archiving and transfer). There is lossyand lossless compression. Compression algorithms can be either general-purpose or designed for specific types of data (e.g., for ...

Using 3DF Zephyr to determine body‐worn camera position

Journal of Forensic Sciences, EarlyView.
Abstract Photogrammetry has been used consistently in forensic settings to document crime scenes three‐dimensionally. Traditionally, a large number of still photos are taken, and information from those photos is used to create a three‐dimensional (3D) model.

Information and affective valence influence judgments of complexity, liking and understanding

British Journal of Psychology, EarlyView.
Abstract Visual complexity is a key factor in perceptual and evaluative judgments. People's representation of visual complexity is constructed from quantitative and structural image features, but it is also influenced by familiarity and expertise. We examined how people represent visual complexity and its impact on perception and evaluation, focusing ...

Splatshop: Efficiently Editing Large Gaussian Splat Models

Computer Graphics Forum, EarlyView.
Abstract We present Splatshop, a highly optimized toolbox for interactive editing (selection, deletion, painting, transformation, …) of 3D Gaussian Splatting models. Utilizing a comprehensive collection of heuristic approaches, we carefully balance between exact and fast rendering to enable precise editing without sacrificing real‐time performance. Our
