Someone please help me with my matlab homework... the cameraman file is an imaginary file btw THANKS!

displayed image by using the figure command. Use of subplot (m, n, k) will help. 1. Again, open the standard image, 'cameraman.tir' with the imread. Filter and display the image with a vertical Sobel edge filter using the command, v imfilter (I,h1). Filter and display the image with a horizontal Sobel edge filter with the command, H imfilter (I,h2). Display both images along with the addition of the two images. 2. Open the standard image, 'cameraman.tif' with the imread() function. Filter the image with an embossing filter and display the image with the same 256-element gray colormap. 3. Again, Open the standard image, "cameraman.tie' with the imread function. Filter the image with a sharpening to -1 0 -1 5 -1 0 -1 01 filter and an edge filer to -1 0; -1 4 -1: 0 -1 0]. Display the images with the same 256-element gray colormap and comment on the differences. 4. Using the images from Problem #3, plot the histogram using the In,v) -hist (x,nbins) command for the same value of nbins. Plot the histograms in different colors on the same graph and display the results. 5. Again, open the standard image, 'cameraman.tif' and display the image. Use the imnoise() command to add 'salt & pepper' noise (sometimes called shot noise') to the image and display the result. Try and remove the added noise with a 3x3 averaging filter using AVG imfilter (I,h) and a 3*3 median filter, MED medfilt2() and display both results. State which one works better
