a real - time computer vision system tracks one or more objects moving in a scene using a target location technique which does not involve searching . the imaging hardware includes a color camera , frame grabber and processor . the software consists of the low - level image grabbing software and a tracking algorithm . the system tracks objects based on the color , motion and / or shape of the object in the image . a color matching function is used to compute three measures of the target &# 39 ; s probable location based on the target color , shape and motion . the method then computes the most probable location of the target using a weighting technique . once the system is running , a graphical user interface displays the live image from the color camera on the computer screen . the operator can then use the mouse to select a target for tracking . the system will then keep track of the moving target in the scene in real - time .
