Abstract: Systems and methods for identifying low cost subterranean paths are presented. Travel costs are assigned to areas of a 3D subterranean model based on geographic and man-made conditions. The model is analyzed to identify low cost paths of travel between points, from an area to a point and vice versa, and between multiple points in a given area. This analysis can be used to help inform planning for the construction of subterranean transport networks such as utility lines and tunnels by highlighting paths with the lowest costs. Similarly, this analysis can be used to identify likely locations for preexisting paths so that they can be explored or interdicted.

Abstract: Systems and methods for improving night vision systems are presented. Broadband multi-level diffractive lenses are used in place of either or both of the objective and eyepiece of traditional night vision systems. By using one or more broadband multi-level diffractive lenses, the size, weight, and weight distribution may be reduced or modified.

Abstract: Systems and methods for performing quality assurance assessments for unattended computer vision counting tools are presented. Classification information is used to generate coefficients for error equations. Digital filters are used to train and update these coefficients. These coefficients are used to determine object count uncertainty ranges for an area of interest.

Abstract: A device and methods for displaying representations of objects, solids, and surfaces volumetrically in a medium containing one or more photochromic compounds comprising at least one UVA light source arranged to project a beam of UVA radiation and irradiate at least one portion of a display volume incorporating at least one display medium which includes at least one photochromic compound. The irradiance of the irradiated portion of the display medium being sufficient for clear-to-colored transitions of voxels of the display medium from a transparent state to a colored state. After a time period after the irradiation, the irradiated voxels activated in the colored state transition by a colored-to-clear transition into the transparent state.

Abstract: Systems and methods for performing quality assurance assessments for unattended computer vision counting tools are presented. Classification information is used to generate coefficients for error equations. Recursive digital filters are used to train and update these coefficients. These coefficients are used to determine object count uncertainty ranges for an area of interest.

Abstract: Systems and methods for automatically optimizing pairs of stereo images are presented. Pixels in an image pair are reprojected from their raw format to a common pixel-space coordinate system. The image pair is masked to remove pixels that do not appear in both images. Each image undergoes a local enhancement process. The local enhancements are processed into a global enhancement for each image of the image pair. A factor is calculated to balance the left and right images with each other. A brightness factor for the image pair is calculated. The enhancements, including the balancing and brightness factors, are then mapped to their respective images.
