Hi, I am new to matlab and looking for some help on where to begin with this project.
Background: I have a material I am stretching, I am taking images of the material with clear markers on the material, using these as signs of changes between each stretch(image).
I am looking for some type of code in which I can identify the distance between points on the material and then work out the change in the location and distance between each point. Here is an image to demonstrate what I mean by this.
Thank you for any help, even pointers on where to begin.

You didn't attach your image so about all I can do is to suggest you start with a simple example, such as my Image Segmentation Tutorial: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 then adapt it to your image(s).
