Deformable channel non‐local network for crowd counting

Electronics Letters, 2023
Both global dependency and local correlation are crucial for solving the scale variation of crowd. However, most of previous methods fail to take two factors into consideration simultaneously.

Smoothly deformable spheres [PDF]

SIGGRAPH ASIA 2016 Technical Briefs, 2016
Existing shape models with spherical topology are typically designed either in the discrete domain using interpolating polygon meshes or in the continuous domain using smooth but non-interpolating schemes such as NURBS. Polygon models and subdivision methods require a large number of parameters to model smooth surfaces.

Quantitative Comparison of Deformable Models in Range Segmentation

Cybernetics and Information Technologies, 2015
In this paper we segment range images by applying three deformable models (the classical Active Contour, the adaptive active contour and the Level Set method). These three methods are used to segment images with planar and curved surface scenes. Then the

Potential Fields as an External Force and Algorithmic Improvements in Deformable Models

ELCVIA Electronic Letters on Computer Vision and Image Analysis, 2003
Deformable Models are extensively used as a Pattern Recognition technique. They are curves defined within an image domain that can be moved under the influence of internal and external forces.

Data-Driven Haptic Modeling and Rendering of Viscoelastic Behavior Using Fractional Derivatives

IEEE Access, 2022
Data-driven modeling and rendering is a general approach in haptics aiming to provide highly accurate haptic perceptual experiences simulating complex real physical dynamics, such as deformable or textured objects.

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Semi-Automatic segmentation of multiple mouse embryos in MR images

BMC Bioinformatics, 2011
Background The motivation behind this paper is to aid the automatic phenotyping of mouse embryos, wherein multiple embryos embedded within a single tube were scanned using Magnetic Resonance Imaging (MRI). Results Our algorithm, a modified version of the

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Underwater Object Classification in SAS Images Based on a Deformable Residual Network and Transfer Learning

Applied Sciences, 2023
To solve the problem of low classification accuracy caused by differences in object types, shapes, and scales in SAS images, an object classification method based on a deformable residual network and transfer learning is proposed.
