There are two algorithms Quantify Mask(s) and Quantify Using Mask that calculate Center of Mass, area (in resolutions), and number of pixels for a selected mask(s). The algorithms work with Boolean, byte, unsigned byte, and short masks.

To apply the Quantify Mask(s) algorithm:
1 Open an image of interest.
2 Create a mask as described in Chapter 8, "Generating masks".
3 Save the mask as Boolean, byte, unsigned byte, or short.
4 Alternatively, you can open the mask file from the disk using the Quantify dialog box options.

Note: the algorithm doesn't work for paint masks.
5 Call Utilities>Quantify> Quantify Mask(s).
6 The algorithm begins to run and the data appear in the Output window. See Figure 50.
7 Later, you can save the data using the File>Save Images option provided by the Output window.

4 Call Utilities>Quantify> Quantify Using Mask.
5 The algorithm begins to run and the data appear in the Output window. See Figure 51.
6 Later, you can save the data using the File>Save Images option provided by the Output window.
Note: the algorithm works with Boolean, byte, unsigned byte, and short masks, but it doesn't work with paint masks.
