An Evaluation of a Region-Growing Algorithm Performing Detection for Automatic Target Recognition

Kitrosser J H (US Department of the Army)
J. Imaging Sci. Technol. vol. 38, no. 4, 1994, pp 311-320

The Night Vision and Electronic Sensors Directorate of the U.S. Army has evaluated a system using infrared radiation for the detection and subsequent classification of target-like objects. The principles underlying the process, its mode of action, and the manner in which it can be usefully employed, are discussed. 16 refs

Kinetics of Crystallization of Ge-As-Te Amorphous Films Induced by Heating and Laser Radiation

Turyanitsa I I, Tsigika V V, Mar'yan M I, Il'chenko A I, Lukich S (Uzhgorod State University)
Sci. Appl. Photogr. vol. 34, no. 3, 1993, pp 321-330

In the design of infra-red sensitive materials containing tellurium it is necessary to understand the rate at which the amorphous phase transforms into the crystalline phase since this causes deterioration of the recording characteristics. This paper describes work performed on Ge-As-Te layers to study the transformations caused by both heat and pulsed infra-red radiation on the amorphous and crystalline structures. 8 refs.
