4 (20 points) Optimal Seam Now that you have your energy images, we must find the optimal seam in it. Using the technique discussed in class, for each of your images, - Use its energy image to compute a seam matrix. - Find the optimal seam in this seam matrix via backtracing. - Superimpose on your color image the optimal seam in red. Additional Details: - We will do vertical seam carving, starting at the top of the image. - You'll likely have to think about how to handle the edge cases. Figure 3 shows an example output
