Automated Dynamic Image Analysis for Particle Size and Shape Classification in Three Dimensions [PDF]

arXiv
We introduce OCULAR, an innovative hardware and software solution for three-dimensional dynamic image analysis of fine particles. Current state-of-the art instruments for dynamic image analysis are largely limited to two-dimensional imaging. However, extensive literature has demonstrated that relying on a single two-dimensional projection for particle ...
