Make it easy for us to help you : attach your image or screenshot as a standard PNG format image so that we can see it right here in the browser without the multistep process of saving your files then switching to MATLAB and writing a script to read the data in and display it.

See my Image Segmentation Tutorial in my File Exchange:

Image Analyst's File Exchange

It's a generic, general purpose demo of how to threshold an image to find blobs, and then measure things about the blobs, and extract certain blobs based on their areas or diameters.
