Geometric Algebra Applications Vol. I: Computer Vision, Graphics and Neurocomputing – Eduardo Bayro-Corrochano

This book presents the theory and applications of an advanced mathematical lan­guage called geometric algebra that greatly helps to express the ideas and concepts and to develop algorithms in the broad domain of robot physics.

In the history of science, without essential mathematical concepts, theories would have not been developed at all. We can observe that in various periods of the history of mathematics and physics, certain stagnation occurred; from time to time, thanks to new mathematical developments, astonishing progress took place. In addition, we see that the knowledge became unavoidably fragmented as researchers attempted to combine different mathematical systems. Each mathematical system brings about some parts of geometry; however, together, these systems constitute a highly redundant system due to an unnecessary multiplicity of representations for geometric concepts. The author expects that due to his persistent efforts to bring to the community geometric algebra for applications as a metalanguage for geometric reasoning, in the near future tremendous progress in computer vision, machine learning, and robotics should take place.

What is geometric algebra? Why is its application so promising? Why should researchers, practitioners, and students make the effort to understand geometric algebra and use it? We want to answer all these questions and convince the reader that becoming acquainted with geometric algebra for applications is a worthy undertaking.

The history of geometric algebra is unusual and quite surprising. In the 1870s, William Kingdon Clifford introduced his geometric algebra, building on the earlier works of Sir William Rowan Hamilton and Hermann Gunther Grassmann. In Clifford’s work, we perceive that he intended to describe the geometric properties of vectors, planes, and higher-dimensional objects. Most physicists encounter the algebra in the guise of Pauli and Dirac matrix algebras of quantum theory. Many roboticists or computer graphic engineers use quaternions for 3D rotation estima­tion and interpolation, as a pointwise approach is too difficult for them to formulate homogeneous transformations of high-order geometric entities.
