Problem 2: Basic Grey Level Transformations (5/5) (a) Read and display an image. (b) Calculate the negative of the image and display it. (c) Perform contrast stretching. You can use the imadjustm function (or similar function from your favorite languageflibrary) to perform the image transformation. Be creative and try to do terrible things to your image. Display the result. Problem 3: Image Transformations (10!!!) (481 only) Image scaling is just one kind of transformation that we could use to modify an image. It belongs to a more general class of transformations called affine transformations. Do some research on affine transformations (Wikipedia is typically a good place to start) and write a function to rotate (only) an image by some number of degrees. (For rotation only, you do not need to use homogenous coordinates, although you can.) Run your code on an example image and show the result. Best if you use small angle values to prevent losing your image entirely
