Hi Aiman Zara,
If you are trying to segment an image then you can do the following
An Image segmentation App will open which will allow you to highlight the specific patches in image. Follow the steps
More information on image segmentation can be found in the following documentation
If you want to crop a part of image and further use the image patch for image processing then take a look at imcrop function
the documentation link is https://in.mathworks.com/help/images/ref/imcrop.html
I hope this helps your query, please accept the answer if it does
See my Image Segmentation Tutorial in my File Exchange:
It's a generic, general purpose demo of how to threshold an image to find blobs, and then measure things about the blobs, and extract certain blobs based on their areas or diameters.
You can also try my other demos in there on color segmentation, or you can try the Color Thresholder on the Apps tab of the tool ribbon.
In a nutshell, here are the essentials of image processing:
mask = grayImage > someThreshold;
props = regionprops('table', mask);
If you want more details, then that's what my tutorial does in well-commented, excruciating detail.
