A central task of computer vision is to automatically recognize objects in real-world scenes. The parameters defining image and object spaces can vary due to lighting conditions, camera calibration and viewing positions. It is therefore desirable to look for geometric properties of the object which remain invariant under such changes. In this paper we present geometric algebra as a complete framework for the theory and computation of projective invariants formed from points and lines in… 
A Geometric Approach for the Theory and Applications of 3D Projective Invariants
TLDR
This work shows that geometric algebra is a very elegant language for expressing projective invariants using n views and Illustrations of the application of such projectic invariants in visual guided grasping, camera self-localization and reconstruction of shape and motion complement the experimental part.
Invariants Theory in Computer Vision and Omnidirectional Vision
TLDR
It is demonstrated that geometric algebra provides a simple mechanism for unifying current approaches in the computation and application of projective invariants using n-uncalibrated cameras and the algebra of incidence in the development of geometric inference rules to extend 3D reconstruction.
Geometric Algebra of Computer Vision
TLDR
This chapter presents a mathematical approach based on geometric algebra for the computation of problems in computer vision that will mainly focus on the geometry of multiple uncalibrated cameras and omnidirectional vision.
Geometric algebra of points, lines, planes and spheres for computer vision and robotics
TLDR
The authors show that CGA deals with the intuition and insight of the geometry and it helps to reduce considerably the computational burden of the problems.
Omnidirectional vision and conformal geometric algebra for visual landmark identification
TLDR
This paper uses a monocular omnidirectional vision system to extract the image features and the conformal geometric algebra to compute the projective invariants from such features, and shows how these features can be used to compute projective and permutation p2-invariants from any kind of omnid directional vision system.
Surface Evolution and Representation using Geometric Algebra
TLDR
By moving from a projective to a conformal representation (5d representation of 3d space), one is able to extend the range of geometrical operations that can be carried out in an efficient and elegant way.
Projective Invariants of D-moments of 2D Grayscale Images
TLDR
This paper proves that projective invariants of images do exist as functions of the generalized moments of images, and extends the traditional definition of moments by considering both the image function and its derivative functions.
Using Geometric Algebra for Optical Motion Capture
TLDR
A series of calibration techniques which use all of the available data simultaneously and produce accurate reconstructions with no complicated calibration equipment or procedures are outlined.
The Complete Set of Independent Affine Moment Invariants of Color Images
TLDR
Two new methods have been proposed to derive moment invariants of images under different group actions that are compatible with known algorithms for pattern recognition and image processing.

TLDR
Geometric algebra is presented as system for analysing the geometry of multiple-view images by giving purely geometric derivations of the constraints, for point and line correspondences in n-views and via a discussion of projective structure.
