kornia/affnet

Pretrained weights for AffNet,

used by kornia.feature.LAFAffineShapeEstimator.

AffNet is a CNN that estimates the 2×2 affine shape matrix for a detected keypoint patch,

making subsequent description invariant to affine transformations. Trained jointly with

HardNet to maximise discriminability of affine-normalised patches. ECCV 2018.
