Almost Everything One Needs to Know About Image Matching Systems
Abstract
This paper describes the overall design and evaluation of map- matching systems. Section 2 describes the problems associated with describing a scene mathematically and with the time and spatial-varying nature of scene signature for various sensor types. This section describes the nature of environmental factors on image dynamics and their impact which can be measured in terms of predictive errors, nonstructured errors, and contrast reversals for various sensor wavelengths. Finally, remedies are discussed which can mitigate the effects of errors due to image dynamics. Section 3 describes the problems associated with reference map construction and discusses the scene selection process by which good reference scenes are progressively screened out from those that are not so good. Section 4 decscribes the compatibility of various classes of algorithms to accommodate each of the four categories of error sources. Ultimately, since the magnitude of these errors is sensor dependent, this section cross correlates algorithm appropriateness for each sensor wavelength. Finally, Section 5 describes the mathematical process behind developing measures for system performance. This section is divided into two parts.
