Problem 2 - Display a subsampled version of the image that only includes the even rows and odd columns As a hint, the resolution of the image will decrease so it will appear blurrier. [ ] def subsampled(im): return im \# Test the function I = read_image_from_file('sports.jpg') plot_image (subsampled(I), 'Subsampled Image', size=(20, 5)); Problem 3 - Convert a color image to grayscale by taking its red, green, and blue channels and combining them with this formula: G rayscale =0.299R+0.587G+0.114B def grayscale(im): return im \# Test the function I= read_image_from_file('sports.jpg') plot_image (grayscale (I), 'Grayscale Image', size =(20,5) ); Problem 4 - Display the negative of the grayscale version of the image. The formula is Negative_Grayscale =255 - Grayscale def negative_grayscale(im): im_gray = grayscale(im) return im_gray \# Test the function I = read_image_from_file('sports.jpg') plot_image(negative_grayscale(I), 'Negative Grayscale Image', size=(20, 5))
