HEASK: Robust homography estimation based on appearance similarity and keypoint correspondences

作者:

Highlights:

• A new loss function is formulated in homography verification.

• The function combines models of keypoint correspondence fitness and appearance similarity.

• Keypoint fitness errors are better characterized with a Laplacian distribution.

• Image similarity is described using the distribution of ECC.

• The algorithm is realized by an improved RANSAC framework.
