Radiant TIN (U)

Overview (U):

(U) Radiant TIN is an effort focused on developing various imagery exploitation "tools." The goal is to improve the usefulness and availability of national imagery and graphic products in support of tactical operations, emphasizing on the needs of lower-echelon units that rely on low-data-rate communications and simple processors for the distribution and processing of operational information.

Description (U):

(U) Radiant TIN comprises the following separate efforts:

- (U) Imagery Compression- Through a process called "decomposition," Radiant TIN software (running on existing tactical data processors where possible) transforms the pixels of a digital image into polynomial equtions desribing straight lines, curves, and shades of gray in the image. These equations, in the form of a binary file, may be transmitted among tactical units as E-mail, using existing communications systems. The size of the binary file and, therefore, the speed of transmission of an image overa given communications circuit, is decided by the operator during the decomposition process- compression ratios in excess of 100:1 are feasible in many situations. At the receive location, a process called "recomposition" is used to recreate a synthetic version of the original image.

- (U) Automatic Change Detection- Radiant TIN algorithms have the potential to automatically detec the differences between two images of the same scene. Because the process relies on a mathematical rather than a pixel-by-pixel comparison, it is not necessary to rectify and mensurate the two images prior to comparing them.

- (U) Automatic Target Recognition - Radiant TIN algorithms offer the potential to automatically detect the presence of objects of tactical interest (e.g., tanks, artillery, aircraft, etc.) in an image. The process searches for a match between mathematical descriptions of objects of tactical interest, stored in a reference file, and objects found in the image.
