SRI’s image analysis system was the first interactive single-user image processing and manipulation system coupled with a high-resolution bit-mapped display. It provided flexible access to 2D image processing tools, including displays at multiple resolutions, perspective projections, and a wide range of image operators.
ImagCalc evolved into the SRI Cartographic Modeling Environment (CME), which supported the interactive creation and manipulation of 3D object models overlaid on imagery. CME was licensed by SRI to a variety of commercial and university groups.
