ECE 101 - Fall 2009 Lab #3 Solutions Results: The license plate reads, “ECE 101 – F’09”. The length of the blur is N = 444. An improperly de-blurred image has “ghosts” of the original image shifted horizontally by a factor such that you see replicas of the original image at different locations. M-files: Lab3.m % Start-up: load lab3.mat ; colormap(map); image(pic); unblur(pic,200); image(ans); % value of N too low % seems like N should be around 450 from new image unblur(pic,450);
