Have you got the image processing toolbox? What does
ver
says?
You'd typically get this error if you don't have the toolbox installed and licensed

You do not have the image processing toolbox installed. You need to install it, assuming it's included in your license.

It appears from your title that filteredThresh might be a gray scale image (like uint8), not a binary image (like logical). bwlabel() expects a binary image. What does this show:
whos filteredThresh
It should say logical.
