Example of blob detection connectivity when finding blue colored blobs.

Blob Detection

This is lab 8 of 12 in the course

by Quanser Inc.

In this lab, students will learn and apply the blob detection (or particle analysis) technique for image processing. They will analyze static and dynamic images to hypothesize the outcome of blob analysis, and then use LabVIEW to perform the analysis and compare the results. They will also experiment to learn how threshold ranges can be used to improve a blob analysis so that particles can be accurately found in an image. Required: Must complete previous labs before starting this lab.
