Deep Dive Virtual Workshop 5. Filtration Analysis - 2. Segmentation and Property Analysis

Image segmentation, or labeling of all voxels, is always the first step of the analysis, and there are many different techniques to perform segmentation. Once the image is segmented, we can start analyzing the basic properties of filtration media and devices. These analyses will include characterization of media, whether the media be fibrous or other material. For example, we can calculate filter component size, orientation, volume percentage, and other parameters. In this episode, we will review image segmentation. Then, we will calculate some basic properties of filter samples and prepare data for simulations.

In this workshop, you will learn:

• How to identify and separate fibers 
• How to analyze fiber properties, including fiber diameter, orientation, and curvature
