In this paper we propose a novel approach for detecting interest points invariant to scale and affine transformations. Our scale and affine invariant detectors are based on the following recent results: (1) Interest points extracted with the Harris detector can be adapted to affine transformations and give repeatable results (geometrically stable). (2) The characteristic scale of a local structure is indicated by a local extremum over scale of normalized derivatives (the Laplacian). (3) The… Expand

Invariant image descriptors and affine morphological scale-space
TLDR
This research report proposes a novel approach to build interest points and descriptors which are invariant to a subclass of affine transformations, based on the so-called Affine Morphological Scale-Space, a non-linear filtering which has been proved to be the natural equivalent of the classic linear scale-space when affine invariance is required.

An invariant interest point detector under image affine transformation
For vision-based mobile robot navigation, images of the same scene may undergo a general affine transformation in the case of significant viewpoint changes. So, a novel method for detecting affineExpand
Affine Invariant Feature Description
TLDR
The proposed descriptor is a weighted histogram of gradient orientations and invariant against scale, in-plane rotation, stretch and skew, which is capable of describing affine transformed regions well, even in case of strong affine image distortions. Expand
ASIFT: A New Framework for Fully Affine Invariant Image Comparison
TLDR
The proposed affine-SIFT (ASIFT), simulates all image views obtainable by varying the two camera axis orientation parameters, namely, the latitude and the longitude angles, left over by the SIFT method, and will be mathematically proved to be fully affine invariant. Expand

Robust Wide Baseline Stereo from Maximally Stable Extremal Regions
TLDR
The wide-baseline stereo problem, i.e. the problem of establishing correspondences between a pair of images taken from different viewpoints, is studied and an efficient and practically fast detection algorithm is presented for an affinely-invariant stable subset of extremal regions, the maximally stable extremal region (MSER).

Wide Baseline Stereo Matching based on Local, Affinely Invariant Regions
TLDR
This work presents an alternative method for extracting invariant regions that does not depend on the presence of edges or corners in the image but is purely intensity-based, and demonstrates the use of such regions for another application, which is wide baseline stereo matching. Expand
