New Applications of the Image Grand Tour

چکیده
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 into one-dimensional space (for each pixel) and then renders these projected values as a gray-scale image. An animation of the projected images is obtained by using different linear combinations of the pixel vectors. While the image grand tour was initially used to highlight mines in a minefield, this paper presents new applications of the image grand tour. We use the IGT to find hidden rock art in photographs from sites in state parks in Texas and to reveal features in satellite imagery from the Multi-angle Imaging SpectroRadiometer (MISR), one of the instruments aboard NASA's Earth Observing System satellite Terra.

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...

Detecting Grand Tours of Europe with Geo-Tags
In his recent, light-hearted article “The Grand Tour”, New Yorker journalist Evan Osnos writes of his time with a Chinese tour group in Europe [12]. Osnos describes a group of thirty eight closelychaperoned tourists undertaking a breakneck bus tour, covering five countries in ten days. He argues that Chinese tourists have formed a distinctively Chinese “grand tour” of Europe. This tour includes...
