How to process images using region properties

I am currently doing particle tracking with Matlab, at the present moment l am on the first stage,'image processing.' I am a Matlab beginner. I have imported my image and processed the particles on the image using the following region properties, centroid, area, bounding box and perimeter. I am still to use eccentricity. My first question is 1) What are all the properties l should use in order to say l have completed image processing for particle tracking? For centroid, area and bounding box, l came out right, but have questions on the region property, 'perimeter,'the coding l used is as follows: BW2 = bwperim(dout,8); imshow(dout) figure (5), imshow(BW2) 2) Is the coding correct? 3) If so, what is its relevance?Is it for selecting specific objects with a certain perimeter range or for calculating perimeters for objects?if it is the latter, how do l display the perimeter values? 4) Is there a sequence for the above region properties? If so, what is the sequence?

See my Image Segmentation Tutorial in my File Exchange http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862. It goes over regionprops and how to measure and filter results.
