1. A system for characterization of the size of a target object comprising:
- a visual input device for receiving a scanned scene image, the scene image including an image of the target object and a background image;
means for determining a boundary of the image of the target object, the boundary being a plurality of transition points between the target object image and the background image;
means for determining a plurality of intermediate sizes of the target object, each of said intermediate sizes determined from three of said transition points on the boundary of the target object, and an image point on the image of the target object, each of said intermediate sizes being along a substantially same direction with respect to a predetermined scan direction; and
means for determining a size characterization of the target object from said plurality of the determined intermediate sizes.

Abstract
The present system and apparatus uses image processing to recognize object size within a scene. The system includes novel image processing apparatus and methods to segment one or more object images from a background image of the scene. A processed image (that can be used to characterize size features) of the object(s) is then compared to stored reference images. The object size is recognized when a match occurs. The system can recognize object sizes independent of number of objects present and the objects may be touching each other and overlapping. The system can be trained to recognize object sizes that it was not originally programmed to recognize.

4. A system for determining a size of target objects having a boundary, the boundary having a radius of curvature, comprising:
-
a visual input device for receiving a scanned scenic image, the scene image including an image of the target objects and a background image; means for determining a boundary of the image of the target object defined as a plurality of transition points between the target object and the background image; means for determining a plurality of intermediate sizes of said target object, each of said plurality of intermediate sizes determined from three points on the boundary of the target object and an image point on the image of the target object, and each of said intermediate sizes being along a same direction with respect to a predetermined scan direction; means for storing a plurality of predetermined reference object size characterizations; means for comparing the plurality of intermediate sizes with one or more of said stored reference object size characterizations and generating a result of said comparing; and means for determining a size of the target object based on said result. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
