I am new to Matlab. I want to crop the highlighted part of the gray image and remove the rest part. How to do that, kindly explain as well. Thanks.

You have not attached the original image. Not the cropped one, and not the one with the red box on it, but the original image. So, did you even try stdfilt()?

If you know the bounding rows and columns, you can do indexing
croppedImage = rgbImage(row1:row2, col1:col2, :);
or use imcrop():
croppedImage = imcrop(rgbImage, [leftCol, topRow, (rightCol-leftCol+1), (bottomRow-topRow+1)]);

Yes, but that was not the original question so I didn't answer that. You could use stdfilt() and threshold and find the bounding box. Search for braille here - I know I've done code for it before.

Zaheer, I'm sure by now you've tried to take my suggestion and use stdfilt() to automatically get the bounding box. You can look at how I did it and compare it to your own.
