METHODS AND SYSTEMS FOR THE DETECTION OF THE INSERTION, REMOVAL, AND CHANGE OF OBJECTS WITHIN A SCENE THROUGH THE USE OF IMAGERY
First Claim
1. A method for detecting insertion, removal, and change of an object of interest through the comparison of a first image and a second image containing a common area of interest, the method comprising using a computing device to identify and prioritize image regions within the images based on changes in feature content over time in a manner that is consistent with the insertion, removal and change of the object of interest, the identification and prioritization including:
- performing a scene registration including aligning image patterns in the first image to those in the second image;
performing a feature content analysis to determine a General Pattern Change (GPC) likelihood of change over time for each pixel in the first and second images;
performing a region identification to group pixels within the first and second images into one or more image regions based upon their likelihood of change; and
performing an image region partitioning to prioritize the one or more image regions according to an image region score for each of the one or more image regions, the image region score being indicative of insertion, removal, and change over time of an object of interest within the common area of interest.

Abstract
Methods and systems for detecting the insertion, removal, and change of objects of interest through the use of imagery are disclosed. In one embodiment, a method includes performing a scene registration including aligning image patterns in the first image to those in the second image; performing a feature content analysis to determine a likelihood of change for each pixel in the first and second images; performing a region identification to group pixels within the first and second images into one or more image regions based upon their likelihood of change; and performing an image region partitioning to prioritize the one or more image regions according to an image region score for each of the one or more image regions, the image region score being indicative of at least one of insertion, removal, and change of an object of interest within the common area of interest. Embodiments of the invention may advantageously provide an autonomous capability to detect the insertion, removal, and change of objects of interest.

9. A method comprising using a computing device to detect at least one of insertion, removal, and change of objects of interest through the comparison of a first image and a second image containing a common area of interest, including:
-
determining a likelihood of change for each of a plurality of portions of the first and second images; grouping the plurality of portions into one or more image regions based upon their likelihood of change; and prioritizing the one or more image regions according to an image region score for each of the one or more image regions, the image region score being indicative of at least one of insertion, removal, and change of an object of interest within the common area of interest. - View Dependent Claims (10, 11, 12, 13, 14)
