These functions include both simple CV kernels such as filters, histogram and affine transform as well as sophisticated CV algorithms including FAST, RANSAC, Connected Components and MSER.

The proposed descriptor is invariant to affine transform, including rotation, translation and scaling.

Considers invariants to traditional transforms translation, rotation, scaling, and affine transform, from a new point of view, which offers new possibilities of designing optimal sets of invariants.
