1. Given the grayscale image, I, below, if the top left location in our image is (x=1,y=1), what would be value of a pixel at location x=2.7,y=3.1, if we were to: (a) Use the nearest neighbor in I. (3pts) (b) Perform interpolation (using the Manhattan distance as our distance function) using I. Leave your answer in terms of fractions (7pts) I=214442303453425423521400112623 2. If the matrix below is the gradient magnitude image G=214442303453425423521400112623 (a) Construct the cost matrix if we assume vertical seams (10pts). (b) What is the optimal seam (2pts)
