UNDER AFFINE TRANSFORMATION
"... which a given convex curve can be affinely transformed, and seek the minimum of L /A, where L denotes perimeter and A the area. This amounts to finding the minimum length for a fixed area, or, what is the same thing, to finding the minimum length under areapreserving affine transformations. In § 2 ..."

Image Metamorphosis By Affine Transformations
, 2005
"... Among the many ways to manipulate an image is a technique known as morphing. Image morphing is a special effect that transforms or morphs one image into another. In this paper we show how this can be done using affine transformations. ..."

Affine Transformations, Polynomials, and
"... In the articles [1] and [3], standard tools and techniques of calculus are used to establish a variety of proportionality results concerning areas defined by the lines tangent to a cubic curve, and by the lengths of certain arcs of a parabola, where the arcs themselves are determined by an areapr ..."

proportionality criterion. We demonstrate here that these results can be viewed as consequences of some basic facts about affine transformations in the plane. 1. AFFINE TRANSFORMATIONS. A splendid source of information about affine transformations is Appendix A of [2]; here are the properties we need. Definition
Learning affine transformations
, 1999
"... Under the assumption of weak perspective, two views of the same planar object are related through an affine transformation. In this paper, we consider the problem of training a simple neural network to learn to predict the parameters of the affine transformation. Although the proposed scheme has sim ..."

"... Affine transformations are a wellknown robustness issue in many multimedia fingerprinting systems. Since it is quite easy with modem computers to apply affine transformations to audio, image and video content, there is an obvious necessity for affine transformation resilient fingerprinting.

Affine Transformations of the Speech Space
, 1992
"... The papers Speaker Normalization of static and dynamic vowel spectral features (J.A.S.A 90, July 1991 pp 6775) and Minimum MeanSquare Error Transformations of Categorical Data to Target Positions (IEEE Trans Sig.Proc,40 Jan 1992, pp1323) by Zahorian and Jagharghi describe an algorithm for transf ..."

for transforming the space of speech sounds so as to improve the accuracy of classification. Classification was accomplished by both backpropagation neural nets and by a Bayesian Maximum Likelihood method on the model of each vowel class being specified by a gaussian distribution. The transformation was an affine
Maximizing Parallelism and Minimizing Synchronization with Affine Transforms
 Parallel Computing
, 1997
"... This paper presents the first algorithm to find the optimal affine transform that maximizes the degree of parallelism while minimizing the degree of synchronization in a program with arbitrary loop nestings and affine data accesses. The problem is formulated without the use of imprecise data depende ..."

"... Abstract. This paper presents a novel approach for detecting affine invariant interest points. Our method can deal with significant affine transformations including large scale changes. Such transformations introduce significant changes in the point location as well as in the scale and the shape of ..."
