This image dataset provides a benchmark for systematic uation of robustness to viewpoint change of the image matching algorithms such as SIFT. The dataset contains two parts: one for absolute tilt test and other for transition tilt test. The transition tilt is a new notion that measures the amount of distortion one view to another [Morel and Yu 09]. It gives a fair and new uation criterion of the affine invariance of classic algorithms.
