Base Image: I used the blue channel as the base image and try to align red and green channel to it.

Sobel Edge Detection: While the base methods worked well for most images, I found that certain images like "emir.tif" were difficult to align with the objective function if I used RGB values as input. Instead of computing SSD on the RGB values of the image directly, I preprocessed the images using a sobel edge detection filter and computed SSD on the filtered image. This led to noticeable improvements visualized below.
