Open Specy

Open Specy classifies and matches spectral data to identify microplastic polymers and support spectral analysis for microplastic pollution research.

Key Features:

• Spectral Processing: Implements smoothing with the Savitzky-Golay filter and polynomial baseline correction using IModPolyFit for preparatory signal processing.
• Identification and Matching: Employs correlation-based matching criteria against an onboard reference library to identify spectra.
• Data Sharing and Reproducibility: Accepts user-contributed spectra into a community library and records session logs to track interactions for reproducibility.
• Community-Driven Growth: Supports expansion of the reference database through community contributions to improve identification coverage and accuracy.
• Comparative Accuracy: Reported evaluations show comparable accuracy to commercial spectral analysis software such as OMNIC Picta and KnowItAll.

Scientific Applications:

• Microplastic Analysis: Identification and classification of microplastic polymers from spectral measurements in environmental research.
• Spectral Data Analysis: General use for analysis and matching of spectral datasets beyond microplastics where comparable spectral identification is required.

Methodology:

Spectral smoothing using the Savitzky-Golay filter, polynomial baseline correction via IModPolyFit, correlation-based matching against a reference library, integration of user-contributed spectra into the library, and session logging for reproducibility.
