Medial Axis Aware Learning of Signed Distance Functions

Computer Graphics Forum, EarlyView.
Abstract We propose a novel variational method to compute a highly accurate global signed distance function (SDF) to a given point cloud. To this end, the jump set of the gradient of the SDF, which coincides with the medial axis of the surface, is explicitly taken into account through a higher‐order variational formulation that enforces linear growth ...

Secured regions of interest (SROIs) in single-pixel imaging

Scientific Reports, 2019
Single-pixel imaging, which is also known as computational ghost imaging, can reconstruct an entire image using one non-spatially resolved detector. However, it often requires a large amount of sampling, severely limiting its application.

Frequency‐Aware Spatial‐Angular Gaussians for Efficient Global Illumination Precomputation and Real‐Time Rendering

Computer Graphics Forum, EarlyView.
Abstract Precomputation and efficient approximate material models are well‐known approaches for achieving real‐time rendering with global illumination. Recent research in radiance fields and in particular 3D Gaussian Splatting has demonstrated the power of Gaussian primitives both to represent radiance and for fast optimization.

Fluid Control with Localized Spacetime Windows

Computer Graphics Forum, EarlyView.
Abstract We present a physics‐based fluid control method utilizing localized spacetime windows, extending force‐based fluid control to substantially larger simulation scales. In many practical editing scenarios, user‐specified objectives affect only a small region of an otherwise satisfactory simulation, resulting in optimal control force distributions

The study of computational ghost imaging in presence of atmospheric turbulence

The influence of atmospheric turbulence is investigated on computational ghost imaging (CGI). The results indicate that turbulence disrupts the resolution of computational ghost imaging, necessitating an alternative high-resolution imaging strategy.

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Seeing AI in the Art & Design Classroom: Exploring the Material Conditions for Critical Visual Literacy

International Journal of Art &Design Education, EarlyView.
Abstract Drawing on an ongoing research project that has brought together teachers and artists as co‐researchers, this paper considers the implications of image‐based Generative AI for teaching and learning in the UK art and design classroom. We explore some of the challenges posed by AI to art and design education in 2026, following a period in which ...

Avoidance habit learning after recovery from anorexia nervosa: An fMRI study

Journal of Child Psychology and Psychiatry, EarlyView.
Background Anorexia Nervosa (AN) has been linked to altered self‐regulatory control processes and maladaptive habitual avoidance behavior. Both goal‐directed and habit systems may be relevant to AN, in which restrictive eating behavior can appear highly deliberate and increasingly automatic over time.
