RANSAC Homography Estimation

Input


Steps

Merge the above images into a Mosaic as follows:

  • Choose one image as the reference image frame.
  • Estimate a homography between each of the remaining images and the reference one. Each homography estimation is done by:
    • Detecting local features in each image
    • Matching feature descriptors between two images
    • Estimating the homography between two images with RANSAC for robustness to wrong keypoint correspondences
  • Warping each image into the reference frame using the estimated homography and composite the warped images into a single mosaic
