Parametric Trajectory Representations for Behaviour Classification [PDF]

open access: yesProcedings of the British Machine Vision Conference 2009, 2009
This paper presents an empirical comparison of strategies for representing motion trajectories with fixed-length vectors. We compare four techniques, which have all previously been adopted in the trajectory classification literature: least-squares cubic spline approximation, the Discrete Fourier Transform, Chebyshev polynomial approximation, and the ...

Power fingerprint identification based on the improved V-I trajectory with color encoding and transferred CBAM-ResNet

open access: yesPLoS ONE, 2023
In power fingerprint identification, feature information is insufficient when using a single feature to identify equipment, and small load data of specific customers, difficult to meet the refined equipment classification needs.

Trajectory Classification Method Based on Probability Density Estimation of Regional Distribution [PDF]

open access: yesJisuanji gongcheng, 2018
Regional distribution is an important feature of moving target,which can be used for target trajectory classification.Previous methods assumed that segments of trajectories distribute as rectangles or Gaussian components,thus the accuracy of trajectory ...

Automated multigravity assist trajectory planning with a modified ant colony algorithm [PDF]

open access: yes, 2010
The paper presents an approach to transcribe a multigravity assist trajectory design problem into an integrated planning and scheduling problem. A modified Ant Colony Optimization (ACO) algorithm is then used to generate optimal plans corresponding to ...

Multi-scale classification of moving objects trajectories [PDF]

open access: yesProceedings. 16th International Conference on Scientific and Statistical Database Management, 2004., 2004
In this paper we propose a classification model for moving objects trajectories. We assume that the classification is based on a multiscale map, and we simply define a trajectory pattern as the sequence of zones an object crosses during its travel. These patterns constitute the basis of classification operators.

On Aircraft Trajectory Type Recognition Based on Frequent Route Patterns [PDF]

open access: yesJisuanji kexue, 2021
With the development of global positioning and radar technology,more and more trajectory data can be collected.In particular,trajectories generated by aircrafts,ships,migratory birds are complicated and varied,and free from any constraints on the ground ...

Research on trajectory hierarchical classification based on deep learning networks [PDF]

open access: yesZhihui kongzhi yu fangzhen
In response to the issue that existing trajectory classification methods fail to fully consider the time series features and spatial structure features of trajectories, leading to a decline in classification accuracy, this paper proposes a trajectory ...

Discovering Heterogeneous Subsequences for Trajectory Classification

open access: yesCoRR, 2019
In this paper we propose a new parameter-free method for trajectory classification which finds the best trajectory partition and dimension combination for robust trajectory classification. Preliminary experiments show that our approach is very promising.
