DVST: Deformable Voxel Set Transformer for 3D Object Detection from Point Clouds
Remote Sensing, 2023 The use of a transformer backbone in LiDAR point-cloud-based models for 3D object detection has recently gained significant interest. The larger receptive field of the transformer backbone improves its representation capability but also results in ...

On matrix models and their q-deformations [PDF]
Journal of High Energy Physics, 2020 AbstractMotivated by the BPS/CFT correspondence, we explore the similarities be- tween the classicalβ-deformed Hermitean matrix model and theq-deformed matrix models associated to 3d$$ \mathcal{N} $$N= 2 supersymmetric gauge theories onD2×qS1and$$ {S}_b^3 $$Sb3by matching parameters of the theories.

Deformable contours: modeling and extraction [PDF]
Proceedings of IEEE Conference on Computer Vision and Pattern Recognition CVPR-94, 1994 This paper considers the problem of modeling and extracting arbitrary deformable contours from noisy images. We propose a global contour model based on a stable and regenerative shape matrix, which is invariant and unique under rigid motions. Combined with Markov random field to model local deformations, this yields prior distribution that exerts ...

DYNAMIC PARTICLE SYSTEMS FOR OBJECT STRUCTURE EXTRACTION
Image Analysis and Stereology, 2011 A new deformable model based on the use of a particle system is introduced. By defining the local behavior of each particle, the system behaves as an active contour model showing a variable topology and regularization properties.

The spherical deformation model [PDF]
Biostatistics, 2003 Miller et al. (1994) describe a model for representing spatial objects with no obvious landmarks. Each object is represented by a global translation and a normal deformation of a sphere. The normal deformation is defined via the orthonormal spherical-harmonic basis.

Deformed yangians and integrable models [PDF]
Czechoslovak Journal of Physics, 1997 Twisted Hopf algebra $sl_ξ(2)$ gives rise to a deformation of the Yangian ${\cal Y}(sl(2))$. The corresponding deformations of the integrable XXX-spin chain and the Gaudin model are discussed.

A path aggregation network with deformable convolution for visual object detection [PDF]
PeerJ Computer ScienceOne of the main challenges encountered in visual object detection is the multi-scale issue. Many approaches have been proposed to tackle this issue. In this article, we propose a novel neck that can perform effective fusion of multi-scale features for a ...

Dead Laying Hens Detection Using TIR-NIR-Depth Images and Deep Learning on a Commercial Farm
Animals, 2023 In large-scale laying hen farming, timely detection of dead chickens helps prevent cross-infection, disease transmission, and economic loss. Dead chicken detection is still performed manually and is one of the major labor costs on commercial farms.
