A Computer Vision-Based Tool for Automatic Segmentation and Size Analysis of Nanoparticles in Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) Images
A collection of Jupyter notebooks for metallography analysis
Processes Excel files to calculate nFRET and CB, applies sigmoid curve fitting, identifies kinetic info, and exports plots and summaries of results
Multichannel light-scattering analysis as a proxy for particle dissolution.
Segments gold-nanoparticle TEM micrographs into per-particle size/shape tables (diameter, aspect ratio, touching groups); feeds the aunp-speciation UV-Vis forward model.
Computer-vision pipeline that turns a micrograph into a dispersion-uniformity number — quadrat D_CV, polarity-symmetric particle detection
