how to separate/crop certain ROI in my image

Hi there,

I have problem with cropping certain ROI in my image...For instance, in my attach file, I have a face image in grayscale....so, what I need to do is crop only on a nose area....what is the built-in function or any sample codes that I can use? I believe many people have done a similar work with me but I couldn't find any of them yet...

Please let me know if anyone knows about it..Thank you in advance

Thank you for your answer Dr. However, what i need is I want to crop it automatically... Any idea on what features can I use to identify the nose in the image then automatically crop it...

Yuu must know the range where your ROI lies and give the range...
