Weakly Supervised Fine-Grained Image Classification via Salient Region Localization and Different Layer Feature Fusion

open access: yesApplied Sciences, 2020
The fine-grained image classification task is about differentiating between different object classes. The difficulties of the task are large intra-class variance and small inter-class variance.

On varieties of optimal algorithms for the computation of bilinear mappings I. the isotropy group of a bilinear mapping

open access: yesTheoretical Computer Science, 1978
AbstractThis paper contains the general frame of a theory of varieties of algorithms for the computation of bilinear mappings. In particular, we shall study linear mappings which operate on algo0rithm varieties. It will be shown that every bilinear mapping Φ defines in a natural way a group of automorphisms operating on the variety of optimal ...

Enhanced Monocular Depth Estimation Using ResNet Backbone and Multiscale Feature Decoding for Precise Object Distance Measurement

open access: yesAdvanced Intelligent Systems, EarlyView.
A lightweight monocular perception framework generates high‐fidelity depth maps and integrates YOLOv8 detection to estimate object‐wise distances from a single RGB image. Evaluated on KITTI and the proposed D‐Far250 dataset, the system demonstrates accurate long‐range perception up to 250 m while maintaining real‐time performance, enabling scalable ...

Self-Bilinear Map from One Way Encoding System and i𝒪

open access: yesInformation
A bilinear map whose domain and target sets are identical is called a self-bilinear map. Original self-bilinear maps are defined over cyclic groups. Since the map itself reveals information about the underlying cyclic group, the Decisional Diffie–Hellman

Bilinearity, rules, and prefrontal cortex

open access: yesFrontiers in Computational Neuroscience, 2007
Humans can be instructed verbally to perform computationally complex cognitive tasks; their performance then improves relatively slowly over the course of practice.

Some integrable maps and their Hirota bilinear forms [PDF]

open access: yes, 2017
We introduce a two-parameter family of birational maps, which reduces to a family previously found by Demskoi, Tran, van der Kamp and Quispel (DTKQ) when one of the parameters is set to zero.

On trilinear and quadrilinear equations associated with the lattice Gel’fand–Dikii hierarchy

open access: yesPartial Differential Equations in Applied Mathematics
Introduced in Zhang et al. (2012), the trilinear Boussinesq equation is the natural form of the equation for the τ-function of the lattice Boussinesq system.

Remote Roca: Integrating Data From Archaeological Survey, Remote Sensing and Geophysics in the Hinterland at the Long‐Lasting Mediterranean Site of Rocavecchia (Apulia, Italy)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This study presents a multi‐method non‐invasive investigation of an approximately 4‐ha area associated with the long‐occupied coastal settlement of Rocavecchia (Apulia, southern Italy), situated between the prehistoric fortified peninsula and the Hellenistic‐Messapian walls.

End-to-End Implicit Object Pose Estimation

open access: yesSensors
To accurately estimate the 6D pose of objects, most methods employ a two-stage algorithm. While such two-stage algorithms achieve high accuracy, they are often slow. Additionally, many approaches utilize encoding–decoding to obtain the 6D pose, with many

Novel Techniques for Void Filling in Glacier Elevation Change Data Sets

open access: yesRemote Sensing, 2020
The increasing availability of digital elevation models (DEMs) facilitates the monitoring of glacier mass balances on local and regional scales. Geodetic glacier mass balances are obtained by differentiating DEMs.
