1 Getting Started
The third dimension represents the number of color bands in the image.
Because the example data is a grayscale image, the third dimension is 1. For
RGB formats, image frames have three bands: red is the first, green is the
second, and blue is the third. The fourth dimension represents the number of
frames that have been acquired from the video stream.
Step 7: Clean Up
When you finish using your image acquisition objects, you can remove them
from memory and clear the MATLAB workspace of the variables associated
with these objects.
delete(vid)
clear
close(gcf)
