A striking group of five images from the JPL Images Processing Laboratory taken from cameras 1 and 2 of the Mars Viking Lander II. "The Viking orbiter cameras returned over 9000 images of Mars during the 6-month nominal mission. Digital image processing was required to produce products suitable for quantitative and qualitative scientific interpretation. Processing included the production of surface elevation data using computer stereophotogrammetric techniques, crater classification based on geomorphological characteristics, and the generation of color products using multiple black-and-white images recorded through spectral filters. The Image Processing Laboratory of the Jet Propulsion Laboratory was responsible for the design, development, and application of the software required to produce these 'second-order' products" (Ruiz, Elliot, Yagi, et al. "IPL processing of the Viking Orbiter Images of Mars", Journal of Geophysical Research, Vol. 82, Issue 28, p. 4189, September 30, 1977).
