Local-adaptive and outlier-tolerant image alignment using RBF approximation

作者:

Highlights:

• Natural images usually cannot be accurately aligned using traditional approaches.

• Up-to-date approaches suffer from unreliable matches and high computational cost.

• Radial basis function approximation is used to efficiently align natural images.

• Incorrect matches are removed by analyzing parameters of the approximation.

• Overfitting issues are addressed by smoothly weighting the image deformations.
