Inkjet Droplets Contours

This dataset provides a structured representation of droplet shapes generated in drop-on-demand (DoD) inkjet experiments, enabling quantitative analysis and data-driven modeling of droplet formation processes. It consists of two main files: HDF5 File: Contour-Based Representation The HDF5 file contains the extracted contours of droplet boundaries, obtained from high-speed images available in the companion dataset (DOI: 10.5281/zenodo.13862494). Each group in the HDF5 file corresponds to a single experimental case (image). For each group: The input parameters (inkjet trigger signal characteristics) are stored as attributes. The droplet contour(s) are stored as arrays of 2D points representing the boundary. A parametrized representation of the contour is provided using Elliptic Fourier Descriptors (EFDs). CSV File: Tabular Parametric Dataset The CSV file contains a tabulated dataset of 274,911 samples, where each row corresponds to one experimental case. Columns include: Trigger signal parameters (input variables) Elliptic Fourier Descriptors (EFDs) representing droplet morphology This file is particularly suited for statistical analysis, regression, and machine learning applications, providing a compact, low-dimensional representation of droplet shapes. Data Processing and Tools: Image processing and contour extraction were performed using our open-source pipeline: https://github.com/DropletDynamics/InkJetDroplet Elliptic Fourier Descriptors were computed using: https://github.com/hbldh/pyefd Licence: This dataset is licensed under CC BY-NC-SA for non-commercial use.If you modify or adapt the dataset, you must share the modified version under the same license (CC BY-NC-SA) and credit the original source.For commercial use, a separate license is required—please contact [e-mail] for details.
