Working with Acquired Image Data

When you trigger an acquisition, the toolbox stores the image data in a memory buffer, a disk file, or both. To work with this data, you must bring it into the MATLAB workspace.

This chapter describes how you use video input object properties and toolbox functions to bring the logged data into the MATLAB workspace.
