Image stitching using homography estimation and RANSAC
- Choose one image as the reference frame.
- Estimate homography between each of the remaining images and the reference image. To estimate homography between two images, we use the following procedure: (a) Detect local features in each image (using SIFT). (b) Extract feature descriptor for each feature point. (c) Match feature descriptors between two images. (d) Robustly estimate homography using RANSAC.
- Warp each image into the reference frame and composite warped images into a single mosaic.
