Abstract
A device detects the location of objects in an environment by receiving an optical image and converting the optical image of the lost object into a color digital image. The device employs software to perform an analysis of the color digital image to detect the location of the one or more objects in the environment by using color and shape characteristics of the one or more objects. The software uses a range of the visible portion of the color space uniquely identified for the type of object in that environment and identifies those pixels in the color digital image that may be possible targets. Intensity of background and object size are used to exclude pixels as possible target objects.
