If I have two images
Image 1: Aligned properly http://i.imgur.com/ui6wTiJ.jpg Aligned properly
Image 2: Not aligned properly http://i.imgur.com/Z05ZfwR.jpg Not aligned properly
My algorithm compares two images but it needs both the images aligned properly. I was thinking of putting some unique marker at top-left corner but is there another way to align the images properly?
