Remote sensing
Nonsystematic distortion
Earth science; Remote sensing
Geometric irregularities on images that are not constant and cannot be predicted from the characteristics of the imaging system.
Stereo base
Earth science; Remote sensing
Distance between a pair of correlative points on a stereo pair that are oriented for stereo viewing.
Fluorescence
Earth science; Remote sensing
Emission of light from a substance following exposure to radiation from an external source.
Acuity
Earth science; Remote sensing
A measure of human ability to perceive spatial variations in a scene. It varies with the spatial frequency, shape, and contrast of the variations, and depends on whether the scene is coloured or ...
Vignetting
Earth science; Remote sensing
A gradual change in overall tone of an image from the centre outwards, caused by the imaging device gathering less radiation from the periphery of its field of view than from the centre. Most ...
Near infrared (NIR)
Earth science; Remote sensing
The shorter wavelength range of the infrared region of the EM spectrum, from 0. 7 to 2. 5 m. It is often divided into very-near infrared (VNIR) covering the range accessible to photographic ...
Training area
Earth science; Remote sensing
A sample of the Earth's surface with known properties; the statistics of the imaged data within the area are used to determine decision boundaries in classification.
