Point to segment distance DTW for online handwriting signals matching

, 2023
International audienceIn this paper, we propose DTW seg , a modified DTW algorithm based on a point-to-segment distance instead of the euclidean point-to-point distance.

Time Series Extrinsic Regression for Smart Agriculture: Field‐Level Crop Yield Prediction From Multisource Agricultural Time Series

Quality and Reliability Engineering International, EarlyView.
ABSTRACT The growing availability of temporal data in agriculture has created new opportunities for data‐driven decision support systems aimed at improving the efficiency, sustainability, and adaptability of agricultural systems. Remote sensing platforms, weather‐related datasets, and field‐management records provide information on crop development and

Remote Sensing‐Based Identification of Habitat Loss for Herbivorous Waterbirds Driven by Wetland Inundation Alterations

Remote Sensing in Ecology and Conservation, EarlyView.
We present a deep learning framework integrating remote sensing and SHAP interpretation to map 22‐year habitat dynamics of herbivorous waterbirds in Dongting Lake. Results show nearly 50% habitat loss, driven primarily by hydrological recession timing rather than static inundation extent.

Artificial Intelligence for Blue Transformation: A Review of Predictive Modeling and Decision Support Systems in Sustainable Aquaculture

Sustainable Development, EarlyView.
ABSTRACT The FAO's “blue transformation” roadmap necessitates a fundamental shift towards precision aquaculture to meet global food security targets while minimizing environmental footprints. This review provides a comprehensive overview of how artificial intelligence (AI) and decision support systems (DSS) serve as pivotal enablers for the “better ...

Computing and Visualizing Dynamic Time Warping Alignments in R: The dtw Package [PDF]

Dynamic time warping is a popular technique for comparing time series, providing both a distance measure that is insensitive to local compression and stretches and the warping which optimally deforms one of the two input series onto the other.

Description des alignements formés par DTW

, 2011
Ce document a pour but de décrire des indices permettant de décrire les alignements formés par DTW entre deux séquences. Il se focalisera surtout sur la description des alignements formés par DTW entre une séquence moyenne et une séquence associée, mais ...

Exploring feature variability in digitally captured signatures—Part I: Variability in genuine signatures and the effects of collection sessions and writing position

Journal of Forensic Sciences, EarlyView.
Abstract Digitally captured signatures (DCSs) pose new challenges for forensic handwriting examination compared with paper‐based signatures. While DCSs provide spatial coordinates, time and force values for forensic examination, the variability of the features derived from these data remains insufficiently understood.

Efficient Word Image Retrieval using Fast DTW Distance Efficient Word Image Retrieval using Fast DTW Distance

, 2020
-Dynamic time warping (DTW) is a popular distance measure used for recognition free document image retrieval. However, it has quadratic complexity and hence is computationally expensive for large scale word image retrieval.

Digit Recognition based on Euclidean and DTW

International Journal of Computer Applications, 2015
paper describes the implementation of two isolated digit recognition techniques and is a comparison between the algorithms implemented. Any digit recognition comprises of mainly two stages feature extraction and similarity evaluation. Here, two feature extraction techniques, namely linear predictive cepstral coefficients (LPCC) and mel frequency ...
