Terrain Synthesis and Authoring based on Iso‐Contours

Computer Graphics Forum, EarlyView.
Abstract Digital terrains are central to realistic landscape depiction, yet authoring tools must balance perceptual realism with intuitive artistic control. We propose a compact vector‐based representation that models terrain as nested iso‐contours, inspired by geomorphology and cartography.

Multi-base compressive sensing procedure with application to ECG signal reconstruction

EURASIP Journal on Advances in Signal Processing, 2021
Standard compressive sensing (CS) scenario assumes a single sparsifying basis used to reconstruct the signals from a small set of incoherent measurements.

Parallel Vectors Extraction using Bézier Clipping

Computer Graphics Forum, EarlyView.
Abstract In this paper, we propose a novel local feature extraction algorithm for the parallel vectors (PV) operator. Our method is based on Bézier clipping, which is a bracketing‐based root finding method that is commonly‐used in computer‐aided geometric design.

Sparse Representation of FHSS Signals in the Hermite Transform Domain

Telfor Journal, 2017
Signal sparsity is exploited in various signal processing approaches. Signal compression, classification, coding, as well as the recently introduced compressed sensing are some examples where the possibility to represent a signal sparsely determines the ...

Computational Approach for Differential Equations with Local and Nonlocal Fractional-Order Differential Operators

Journal of Mathematics, 2023
Laplace transform has been used for solving differential equations of fractional order either PDEs or ODEs. However, using the Laplace transform sometimes leads to solutions in Laplace space that are not readily invertible to the real domain by ...

Circles of Confidence for Multi‐Label Geometry Completion

Computer Graphics Forum, EarlyView.
Abstract Inside–outside classification is widely used for geometry processing tasks such as surface reconstruction, geometry completion, and calculating signed distance fields. We introduce a new integral formulation of this problem, which assigns confidence scores that points are inside or outside, given incomplete boundary geometry.

Semiological features of epilepsy seizures and paroxysmal non‐epileptic events in children: A systematic review and meta‐analysis

Developmental Medicine &Child Neurology, EarlyView.
Pediatric paroxysmal non‐epileptic events (PNEs) are frequently misdiagnosed as epilepsy. We systematically reviewed and synthesized 40 studies, including 3123 video‐EEG monitored pediatric patients. Epileptic seizures in infants (1 month–3 years) typically presented as arrest, while in children and adolescents (1 month–21 years) they manifested as ...

Chronic Health Condition Trajectories and Multimorbidity in Older Adults With Intellectual Disability: A Brief Report of 15 years of Longitudinal Evidence From IDS‐TILDA

Journal of Intellectual Disability Research, EarlyView.
ABSTRACT Background Adults with intellectual disability experience significant health issues that increase with age. Longitudinal analyses offer important evidence on how the trajectories of these conditions' develop and change. Methods Data were drawn from five waves of IDS‐TILDA, with a nationally representative sample of over 700 adults with ...
