Feature extraction and analysis

The Blob Analysis step is used to identify, count, locate and measure basic features and objects (i.e., blobs) in order to determine presence and position, and enable further inspection. The step works by segmenting images, where blobs are separated from the background and one another, before quickly identifying the blobs. Over 50 characteristics can be measured and these measurements can be used to eliminate or keep certain blobs.
