System for generalizing objects and features in an image
First Claim
1. A self-calibrating, self-determining method of generalizing objects or features in an image, the steps comprising:
- a) retrieving an original image in pixel form;
b) generating groups having a set of values indicating a number of regions in each segmented image;
c) monitoring a slope and slope change of a scene characteristic (SC) curve;
d) establishing at least one stopping point; and
e) generating at least one segmented image corresponding to each of said at least one stopping point.

Abstract
The present invention features the use of the fundamental concept of color perception and multi-level resolution to perform scene segmentation and object/feature extraction in the context of self-determining and self-calibration modes. The technique uses only a single image, instead of multiple images as the input to generate segmented images. Moreover, a flexible and arbitrary scheme is incorporated, rather than a fixed scheme of segmentation analysis. The process allows users to perform digital analysis using any appropriate means for object extraction after an image is segmented. First, an image is retrieved. The image is then transformed into at least two distinct bands. Each transformed image is then projected into a color domain or a multi-level resolution setting. A segmented image is then created from all of the transformed images. The segmented image is analyzed to identify objects. Object identification is achieved by matching a segmented region against an image library. A featureless library contains full shape, partial shape and real-world images in a dual library system. The depth contours and height-above-ground structural components constitute a dual library. Also provided is a mathematical model called a Parzen window-based statistical/neural network classifier, which forms an integral part of this featureless dual library object identification system. All images are considered three-dimensional. Laser radar based 3-D images represent a special case.
