In this chapter, you’ll continue to work on the transformation of digital images. In the previous chapter, you modified mainly the pixel color information for an image, using the built-in and custom functions in Processing. In this chapter, you will focus on deforming the pixel grid of the image without changing the image content.

Using Gale transforms in computational geometry
Mathematical Programming, 1988The author gives an interesting example of a powerful solution technique in computational geometry. For the transformation techniques of Gale transforms, which are known from combinatorial geometry, efficient algorithmic solutions for particular questions from theory of convex hulls, visibility, and scene analysis are given. The results give answers to

Abel Transform and Integral Geometry
2004In 1917 Radon published his famous paper [26] where he defined the operator which we call today the Radon transform. I already had a chance to write about this very significant paper [17]. Let us remind that Radon considers the problem of the reconstruction of a function of 2 variables f(x, y) through its integrals F(l) along all lines l.

Kleinian Transformation Geometry
The American Mathematical Monthly, 1977In this article we shall give a modern interpretation of transformation geometry. This subject has recently become of great interest to mathematics educators for use in kindergarten to high school, but has been paid too little attention at the college level.

The geometry of regulating transformers
IEEE Transactions on Magnetics, 1978Ferroresonant, ballast, and current-limiting transformers are similar in geometxy. Optimization of weight, losses, or cost can result in different choices for the shape (core or shell) and proportions of the lamination. In the ferroresonant transformer, the problem of saturation losses, noise and stray flux can be alleviated by altering the geometry to

Topology and Transformations in High School Geometry
Educational Studies in Mathematics, 1971There is a simple and natural way of regarding Euclidean geometry that has been largely ignored in the teaching of geometry. This is the view that Euclidean geometry is the mathematical study of the size and shape attributes of physical objects.
