Image division for segmentation

Hello, I have a binarized image and I need to divide it into parts for segmentation. How could I do that? Thanks

Hi @Pablo Márquez,

Assuming that you need help in Image Segmentation, you can use the "greythresh" method or the Image Segmentor App.

You can visit these documentation pages for more information:

https://in.mathworks.com/help/images/image-segmentation.html -- Different types of Segmentation techniques including greythresh

Assuming you need help in Image Division, you can look at this answer:

What you describe is vague. You're going to have to clearly explain what you have and what you intend to do.

Of course, DGM, I'm sorry. What I have is the following image, that is a serrated chip formation obtained from a machining process:

You can see the original image on the left, and the binarized one on the right. What I need to do is to separate each single tooth getting a black space betwen them, like this:

I've got the pixel coordinates of the peaks and the valleys of the white area, so I think I could draw a black line from each peak to each valley, but I don't know how.

Thanks mate.

Thanks Saha, I'll try with the "greythresh" method.

Hi Pablo, in MATLAB, you can use the regionprops function to divide a binarized image into parts for segmentation.

Here is the documentation for the same: Measure properties of image regions - MATLAB regionprops - MathWorks India.

I hope this helps,

Thanks.

I'll try with regionprops, I've just seen the command. I think this can be the solution.

Thank you Keerthi.
