I have this image I want to identify the boundaries of the grey shapes and then save the outputs (the boundaries) in an image. Any advise?

Edge Detection can be used to identify the boundaries. Refer here for more information.

As a starting point try imbinarize. It uses Otsu's method for segmentation.
