Image grand tour
The image grand tour is a method for visualizing multispectral or multiple registered images. In many settings, several registered images of the same scene are collected. This most often happens when multispectral images are collected, but may happen in other settings as well. A multispectral image can be viewed as an image in which each pixel has a multivariate vector attached. The desired goa...
متن کاملA Grand Tour of Pedals of Conics
We describe the pedal curves of conics and some of their relations to origami folding axioms. There are nine basic types of pedals depending on the location of the pedal point with respect to the conic. We illustrate the different pedals in our tour.
متن کاملThe Grand Tour in k-Dimensions1
The grand tour introduced by Asimov (1985) is based on the idea that one method of searching for structure in ddimensional data is to “look at it from all possible angles," more mathematically, to project the data sequentially in to all possible two-planes. The collection of two-planes in a d-dimensional space is called a Grassmannian manifold. A key feature of the grand tour is that the projec...
متن کاملNew Applications of the Image Grand Tour
The image grand tour (IGT) is a method for visualizing multispectral images or multiple registered images. Such images can be described as having a multivariate pixel vector associated with each pixel. Examples are the RGB values of a photograph or the multiple spectral and infrared readings from remote sensing satellites. The image grand tour projects a linear combination of the pixel vectors ...
متن کاملFunctional Projection Pursuit
This article describes the adaption of exploratory projection pursuit for use with functional data. The aim is to nd \interesting" projections of functional data: e.g. to separate curves into meaningful clusters. Functional data are projected onto low-dimensional subspaces determined by a projection function using a suitable inner product. Such a projection is rapidly computed by representing d...
