# Can I simultaneously remove salt and pepper noise and improve the image resolution?

What should my approach be towards designing a filter that can simultaneously remove salt & pepper noise and improve the resolution?

• Your question needs some more details. "Resolution" is a somewhat vague term; do you mean you want to remove speckle noise while sharpening the image at the same time? – Jason R Dec 10 '11 at 17:31
• yes that would be it – vini Dec 11 '11 at 9:27
• Why does it need to be done simultaneously ? Why not use two filters ? – Paul R Dec 11 '11 at 12:27
• am sorry for giving you such a hard time i am new to MATLAB and image processing.. Yes two or more filters that would get the job done is what i want to undertake – vini Dec 11 '11 at 15:51
