Mosaics

---

To select corners I used the starter code for computing harris corners. Then I applied adaptive non-maximal suppression to select an even distribution of significant points.

I then extracted features by sub-sampling from the gaussian blurred image. I then paired the points based on these features and thresholded them based on the ration of the first and second nearest neight; this further reduced the number of points.
For the final mosaics, I used the same method of calculating homographies and merging the aligned images as for part A. I think the results turned out very well except for the room panorama. I believe this did not turn out as well because there were very few corners to detect due to the walls and there were many false matches between points because the walls are very uniform.
