The goal is to detect heart rate, heart rate variability, and other health metrics at a distance without requiring body contact. The data can be readily loaded into MATLAB or Python, or parsed using any HDF5-compatible software.</p>Human vs. Machine: Comparing Urban Condition Classification Methods from Vehicular Visionhttps://jclds139.github.io/publications/gersey-etal-2025-human-vs/Sat, 01 Nov 2025 00:00:00 +0000https://jclds139.github.io/publications/gersey-etal-2025-human-vs/<p>Add the <strong>full text</strong> or <strong>supplementary notes</strong> for the publication here using Markdown formatting.</p>Robust Piglet Nursing Behavior Monitoring through Multi-Modal Fusion of Computer Vision and Ambient Floor Vibrationhttps://jclds139.github.io/publications/dong-etal-2025-robust-piglet/Sat, 01 Nov 2025 00:00:00 +0000https://jclds139.github.io/publications/dong-etal-2025-robust-piglet/VibraFarrow: Pig Farrowing Time Prediction Using Ambient Floor Vibrationshttps://jclds139.github.io/publications/cao-etal-2025-vibra-farrow-pig/Sat, 01 Nov 2025 00:00:00 +0000https://jclds139.github.io/publications/cao-etal-2025-vibra-farrow-pig/<p>Add the <strong>full text</strong> or <strong>supplementary notes</strong> for the publication here using Markdown formatting.</p>ViLA: Leveraging General-Purpose Audio for Training Vibration-Based Stadium Crowd Monitoring Modelshttps://jclds139.github.io/publications/chang-etal-2025-vi-la-leveraging/Sat, 01 Nov 2025 00:00:00 +0000https://jclds139.github.io/publications/chang-etal-2025-vi-la-leveraging/<p>Add the <strong>full text</strong> or <strong>supplementary notes</strong> for the publication here using Markdown formatting.</p>ViLA: Leveraging General-Purpose Audio for Training Vibration-Based Stadium Crowd Monitoring Modelshttps://jclds139.github.io/publications/vi-la/Sat, 01 Nov 2025 00:00:00 +0000https://jclds139.github.io/publications/vi-la/<p>Crowd monitoring in sports stadiums is important to enhance public safety and improve audience experience. Existing approaches mainly rely on manual observation, cameras, and microphones, which can be disruptive and often raise privacy issues. Recently, floor vibration sensing has emerged as a less disruptive and more non-intrusive method for crowd monitoring in sports stadiums. However, because vibration-based crowd monitoring is newly developed, open-source datasets are lacking, making it challenging to develop data-driven models. In this paper, we introduce Vibration Leverages Audio (ViLA), a vibration-based crowd monitoring method that reduces the reliance on labeled data by pre-training with unlabeled cross-modality data. Specifically, ViLA is first pre-trained on general-purpose audio data in an unsupervised manner, and then fine-tuned with a limited amount of labeled vibration data in sensing domains. Through this approach, ViLA learns general spectral pattern representations from audio, then adapts this knowledge to vibrations. By leveraging general-purpose audio datasets, ViLA reduces the reliance on large quantities of domain-specific vibration data. This is particularly important in sensing environments characterized by high data variance and limited sensing durations, such as sports games. Our real-world experiments demonstrate that pre-training the vibration model using publicly available audio data (YouTube clips) achieved up to a 5.8X error reduction compared to the model without audio pre-training.</p>GeoMCU: Adaptable and Resilient Low-Noise Sensing Platform for Structural Vibrationshttps://jclds139.github.io/publications/geomcu-pre/Mon, 01 Sep 2025 00:00:00 +0000https://jclds139.github.io/publications/geomcu-pre/Poster Abstract: Leveraging General-Purpose Audio Datasets for Vibration-Based Crowd Monitoring in Stadiumshttps://jclds139.github.io/publications/chang-etal-2025-poster-abstract/Thu, 01 May 2025 00:00:00 +0000https://jclds139.github.io/publications/chang-etal-2025-poster-abstract/Poster Abstract: Multiscale Vibration Sensing for Activity and Vital Signs Monitoring in Pig Penshttps://jclds139.github.io/publications/codling-etal-2025-poster-abstract/Thu, 01 May 2025 00:00:00 +0000https://jclds139.github.io/publications/codling-etal-2025-poster-abstract/Poster Abstract: On-Shelf Weight Difference Estimation through Active Vibration Sensinghttps://jclds139.github.io/publications/zhang-etal-2025-poster-abstract/Thu, 01 May 2025 00:00:00 +0000https://jclds139.github.io/publications/zhang-etal-2025-poster-abstract/Poster Abstract: Sniffing out the City -
