Develop a Matlab function to geometrically transform the input image (i.e., scale, rotate or translate) using affine transformations discussed in the class. Following are the specific requirements:

• Your function must accept following three parameters: o name of the input image (which is in the same folder as your Matlab function) o a scalar value (1 = scaling, 2 = rotation, or 3 = translation) for the specific geometric transform to be performed o a vector [x y θ] denoting the transform parameters (x and y values are used in case of scaling or translation, and θ value is used for rotation)

• Show the input image along with transformed output image using subplot function. Both images must be shown in one figure with appropriate titles. Note: You CANNOT use the direct Matlab functions such as imscale, imrotate, and imtranslate for transforming the image, i.e., you must implement the full affine transformation algorithm
