Joint analysis of visible and infrared images

By: , and 



Analysis of data combining daytime visible reflected, daytime IR emitted, and nighttime IR emitted images allows us to isolate the physical effects of topography, albedo, and thermal inertia. To a good approximation, these physical influences interact linearly so that maps showing topographic shading, albedo, and relative thermal inertia can be produced by simple algebraic manipulation of the co-registered images. The shading map resembles an airbrush, shaded relief portrayal of the surface, and can be used as the input for quantitative reconstruction of topography by photoclinometry (shape-fromshading). We demonstrate the method with imagery from the NASA 2001 Mars Odyssey Thermal Emission Imaging System (THEMIS), a dataset that could support mapping most of Mars in this way at 100 m resolution.
