Abstract: A processor includes a plurality of packed data registers. The processor also includes a decode unit to decode a packed variable length code point length determination instruction. The instruction is to indicate a first source packed data that is to have a plurality of packed variable length code points that are each to represent a character. The instruction is also to indicate a destination storage location. The processor also has an execution unit coupled with the decode unit and the packed data registers. The execution unit, in response to the instruction, is to store a result packed data in the indicated destination storage location. The result packed data is to have a length for each of the plurality of the packed variable length code points. Other processors, methods, systems, and instructions are also disclosed.

Abstract: A method and an apparatus are disclosed that extract digital elevation data from a pair of stereo images with two corresponding sets of airborne control data associated with each image of the stereo image pair. Point and edge features are identified from the stereo image pair, projected from respective camera stations of the stereo images onto a horizontal projection plane using respective set of airborne control dam including respective positions of a camera station, the interior orientation and calibration data of the camera, respective roll angles, respective pitch angles, respective yaw angles of each image, and respective flight bearing angles. The space coordinate of each projection are compared in object space to obtain an object-space parallax. The topographic elevation of each feature is derived from said object-space parallax, a base length, and the altitude of a camera station autonomously to eliminate the need for stereoscopic viewing device or ground control data.

Abstract: A method and an apparatus are disclosed that, when used in an airborne environment, acquire spatial imagery, that are instantaneous pictures of one or more terrestrial scenes, and the absolute geophysical coordinates (Latitude and Longitude) of ground objects simultaneously. Any number of series of terrestrial images and the absolute geophysical coordinate information are recorded digitally. The absolute geophysical coordinate information is displayed in real-time. The terrestrial imagery and the absolute geophysical coordinate coordinates are displayed and queried in near real-time. Thus, a new type of digital maps, comprising a two-dimensional terrestrial image and the absolute geophysical coordinates of any terrestrial objects in the image, is obtained using solely digitally-recorded spatial data on an original, unprocessed mission medium, or any secondary media. Near real-time images and accurate longitude and latitude coordinates can be displayed and queried before the aircraft lands.
