The goal of the practical session is to automatically stitch images acquired by a
panning camera into a mosaic as illustrated in images below.
Algorithm outline:
1. Choose one image as the reference frame.
2. Estimate homography between each of the remaining images and the
reference image. To estimate homography between two images use the following
procedure:
a. Detect local features in each image.
b. Extract feature descriptor for each feature point.
c. Match feature descriptors between two images.
d. Robustly estimate homography using RANSAC.
3. Warp each image into the reference frame and composite warped images
into a single mosaic.
