Hy everyone, I'm a newbie in Image processing Toolbox. I'm stuck with a problem regarding image segmentation. I have a file with CT images of a thorax. I'd like to implement a code able to perform the segmentation of the external contour of the thorax for each slice. I've theoretical notions but no idea where to start with Matlab. My idea would be using a region growing algorithm Could someone give me a hint? It would be very precious. Thanks

I doubt you need region growing. Maybe simple thresholding would work. First off, see my Image Segmentation Tutorial: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862&sort=downloads_desc
Next see some medical segmentation demos that I've attached.
By the way, you said you attached a .mat file, but you actually did not.
