How can I do graph matching?

Hi,

I have image which has genes in it. These images are refreshed in every 5 minutes. In this 5 minutes the gene can grow/shrink, move & rotate. A new gene can also pop in the image. Is there any way to graph match between same genes after 5 minutes?

I can't do it becuase the gene changes it size and moves too.

Anyone suggesting function which I can use would be very helpful.

Hi,

I understand that you are representing every gene as a graph and want to compare two genes after the image gets updated.

You can store the graph before and after the updating of the image using MATLAB graph library .

For comparing the two graphs you can use the isisomorphicfunction

Hi,

I am working on tracking of the genes. Basically I am using DIP and Compuer Vision tool to achieve this. Thanks for your suggesion.

It sounds like you're not working with a network graph object but with a series of images. If so something more along the lines of the Tracking and Motion Estimation examples in Computer Vision Toolbox may be a better fit for what you're trying to do than the isisomorphic function and a graph object. The "Tracking Pedestrians from a Moving Car" example even talks about how to handle lost or new tracks, which handles among other things people leaving or entering the frame. That sounds similar to your goal.
