OrsaHomography
General software features
This software registers two images by homography. This registration is meaningful in the two following situations:
- no motion of optical center (only rotation and focal change), or
- the observed scene is planar (painting, poster, aerial photo from high altitude...)
The software detects SIFT matching candidate points, then it sorts correct and outlier correspondences thanks to a variant of the robust estimation algorithm RANSAC. This variant uses the a contrario framework to estimate automatically the discrimination threshold.
As output, the user gets a list of matching interest points, the homography matrix, registered images, and a panorama built from the registered images by transparency.
