EXCUSE ME ,,, use ( a gray image.tiff ) from your choice and solve this questions in MATLAB

1.Find or develop a program for adding Gaussian, and salt-and-pepper (impulse) noise to the image. The type of the noise should be determined through an input of the function. In the case of Gaussian white noise, mean and variance of the noise are the other inputs, and in the case of impulse noise, the probability of each of the two noise components should be specified. This is a generic project, in the sense that the program developed here is used in several of the next projects 2. Apply your noise generator function to image.tif. 3. Denoise the image of part (ii) by applying filtering techniques in frequency domain.
