[From equivalent
EP0685814A2]
The present system and apparatus uses image processing to recognize objects within a scene. The system includes an illumination source for illuminating the scene. By controlling the illumination source, an image processing system can take a first digitize image of the scene with the object illuminated a higher level and a second digitized image with the object illuminated at a lower level. Using an algorithm, the object(s) image is segmented from a background image of the scene by a comparison of the two digitized images taken. A processed image (that can be used to characterize features) of the object(s) is then compared to stored reference images. The object is recognized when a match occurs. The system can recognize objects independent of size and number and can be trained to recognize objects that it was not originally programmed to recognize.

1. A system for recognizing objects comprising:
- a) a light source for illuminating the object, the light source having a non-monochromatic light frequency distribution that is constant over a period of time;
- b) a computer system having a visual input device for creating an scene image including a target object image and a background image, a memory storage, and an algorithm for segmenting an object image from a background image in the scene image;
- c) a plurality of reference normalized characterizations, each of a feature associated with a segmented reference object, the reference characterizations being stored in the computer memory storage; and
- d) one or more target normalized characterizations, each of a feature of a segmented target object image, the segmented target object image segmented from the scene by the algorithm,
whereby a target normalized characterization is compared with one or more reference normalized characterizations and the target object is recognized as the associated reference object if the target and reference characterizations match.
