On Affine Invariant Descriptors Related to SIFT
Using a classical result on algebraic invariants of the unimodular group, we present in this paper some basic geometric affine invariant quantities, and we use them to construct some distinctive descriptors for object detection. Although full affine invariance cannot be guaranteed due to noncommutativity of camera blur with affine maps and the domain problem (that is, the difficulty of finding ...
متن کاملRobust Affine Invariant Descriptors
An approach is developed for the extraction of affine invariant descriptors by cutting object into slices. Gray values associated with every pixel in each slice are summed up to construct affine invariant descriptors. As a result, these descriptors are very robust to additive noise. In order to establish slices of correspondence between an object and its affine transformed version, general cont...
متن کاملAffine Invariant Interesting Descriptors
Component trees or level set graphs have proved to be efficient tools for the extraction of stable features in many image analysis and understanding applications. In this paper, we explore the relation between level sets as feature descriptors and curvature scale-space. While most classical image feature detectors are based on linear scale-space, affine-invariant descriptors can be related to t...
متن کاملObject descriptors invariant to affine distortions
The Trace transform is a generalisation of the Radon transform that allows us to construct image features that are invariant to a chosen group of image transformations. In this paper we propose functionals which can be computed from the image function, and which can be used to describe objects in a way that is invariant to the group of affine transforms. We demonstrate the usefulness of the con...
متن کاملSpatially-Sensitive Affine-Invariant Image Descriptors
Invariant image descriptors play an important role in many computer vision and pattern recognition problems such as image search and retrieval. A dominant paradigm today is that of ``bags of features'', a representation of images as distributions of primitive visual elements. The main disadvantage of this approach is the loss of spatial relations between features, which often carry important in...
