Procedure:
1. Extract SIFT features for all twelve test images as well as the reference image (ref.jpg). Match
the reference image to each test image and keep all matches. Visualize top 10 matches for each
test image (your solution document should have 12 pictures).
2. For each test image use the top 3 matches from the previous step to solve the transformation
between the features in the two images. Which transformation did you use?
3. For each test image count the number of inliers for the transformation you computed in the
previous step. Explain how you found the inliers. In your solution document, please rank all the
images according to the number of inliers. That is, first show the image which has the most inliers,
then the image with second highest number of inliers, etc.
4. Take the test image that had the most inliers. Re-compute the transformation using all the inlier
matches. Visualize the transformation by plotting the rectangle from the reference image
transformed to the second image with the computed transformation.
