title: FR-GESTURE

description: The FR-GESTURE dataset consists of 3312 RGBD pairs corresponding to 12 hand signals for guiding UGVs in first response scenarios.

It was captured by two Intel RealSense depth cameras positioned in two different heights (low and high) with arbitrary perception angle. Each participant was asked to perform each gesture at 6 or 7 different distances, to increase diversity and therefore make the classifiers robust to multi-distance gesture recognition.

Two experimental protocols are introduced:



Uniform protocol (uniform_protocol_3312.json): The samples are randomly distributed into train/val/test partitions, with 2304/504/504 samples respectively. The classes within each split are equally distributed to avoid issues due to class imbalance.

Subject independent protocol (subject_independent_protocol_3312.json): This protocol aims to evaluate the generalization ability of the models to unseen subjects. Each split contains instances performed by different signers (who do not participate in more than one split). The train (s2, s3, s4, s5, s6), val (s1) and test (s0) splits contain 2304, 504 and 504 samples, respectively.


Information for each sample (including camera height and approximate distance) can be found in the entire dataset json (entire_dataset_3312.json).

The Classes folder contains the definition of each class. 

The dataset was collected in the context of TRIFFID project [1] and related study on vision-based gesture recognition [2]. 

Please consider citing the related paper [3] if you find this dataset useful for your purposes.

We would like to thank many members of HUA Computer Vision Group for participating in the data gathering procedure.

title: Code Script and Outputs for the Spatial Phonon Framework

description: This Zenodo record contains the reproducibility package for the manuscript Spatial Phonons: A Phenomenological Viscous Dark Energy Approach to DESI (submitted to the Journal of Astrophysics and Astronomy). The archive includes the Python analysis script (Statistical_Fit.py), the primary numerical output in JSON format (fit_results.json), and the LaTeX snippet used to typeset the compressed likelihood comparison and best fit summary (w0wa_compressed.tex). 

The script implements the CPL mapping and the covariance weighted comparison against the DESI DR1 compressed Gaussian constraints in the $(w_0,w_a)$ plane and writes the fitted parameters and derived quantities to the accompanying JSON file. The compressed .tex file is generated from the same outputs and is intended to be included directly in the manuscript source.

Usage: run Statistical_Fit.py in a standard Python environment. The analysis requires common scientific Python packages. The DESI DR1 compressed likelihood products used as external inputs are publicly available from the DESI collaboration data release pages, as cited in the manuscript.

If you use this package, please cite the associated Zenodo DOI and the final journal article once available.
