Abstract: A method of target acquisition and lock-on-launch strike capability of self uided explosive canisters, such as imaging missile systems and imaging artillery projectiles, by launching an imaging sensor platform over the battlefield area and transmitting imagery of the battlefield to an image processing computer system and an image receiving on-board microcomputer. The sensor platform may be an artillery television camera fired over the battlefield and parachute deployed, or an airlift sensor platform aboard a helicopter or the like. The image processing computer system is comprised of an automatic target cueing system and CRT display in which the system displays cued targets on the CRT. The method has an important man-in-the-loop, as a crew-chief, who examines the cued targets on the CRT and eliminates false targets, such as a bush or rock, and annotates selected targets to be struck by the explosive canisters.

Abstract: A technique for DC restoration in AC coupled display systems which includes istogramming, more specifically calculation of histogram values, of the difference in gray levels between two adjacent picture lines on a picture element by picture element (PIXEL-by-PIXEL) basis. The gray level obtaining the maximum number of occurrences is considered the mode of the histogram values. This mode used as an addition factor to every PIXEL of one of the lines, to add a predominating background level or DC component thereto, which is used to create the difference of gray levels between the next two adjacent picture lines. This addition sequence is carried on throughout the entire image frame.
