How to create mask of an image

Question

Jim 2011-9-14

Hi,

I have 10 images of same object(in matrix form)(.txt file) of same size and and same class

I converted from matrix to grayscale using mat2gray command

I calculated the mean of 10 images using

mean(cat(3,IMG1,IMG2,IMG3,IMG4,IMG5,IMG6,IMG7,IMG8,IMG9,IMG10),3)

and this gives me a new image with mean of pixel values of 10 images

Now I have to create mask of the image using the threshold value of the new image

Can anyone suggest something about this?

Thanks in advance
