METHODS AND APPARATUS FOR AUTOMATED TRUE OBJECT-BASED IMAGE ANALYSIS AND RETRIEVAL
First Claim
1. A computerized system for automated retrieval of images from an unstructured repository, the computerized system comprising:
- an image locator that automatically locates images for analysis within the repository to populate a region of interest (ROI) database that contains searchable entries representing images stored in the repository;
an ROI classifier that segments one or more images located by the image locator into a plurality of ROIs, each ROI containing image content associated with one or more actual features of a physical object in the ROI, the ROI classifier having at least one computer-implemented transform filter adapted to extract one or more physical descriptors from the image content for each ROI to be stored in the ROI database as a physical feature vector, each physical descriptor corresponding to at least one of the one or more actual features of a given physical object in the ROI associated with the image content; and
an ROI query module adapted to search the ROI database for images containing content associated with at least one true physical object.

Abstract
An automated and extensible system is provided for the analysis and retrieval of images based on region-of-interest (ROI) analysis of one or more true objects depicted by an image. The system uses an ROI database that is a relational or analytical database containing searchable vectors representing images stored in a repository. Entries in the ROI database are created by an image locator and ROI classifier that locate images within the repository and extract relevant information to be stored in the ROI database. The ROI classifier analyzes objects in an image to arrive at actual features of the true object. Graphical searches may also be performed.

16. A computer-implemented method for automated retrieval of images from an unstructured repository, the method comprising:
-
automatically locating images for analysis within the repository; populating a region of interest (ROI) database with the located images, the ROI database containing searchable entries representing images stored in the repository; segmenting the located images into a plurality of regions of interest (ROIs), each ROI containing content associated with one or more actual features of a physical object; extracting at least one physical descriptor from the content for each ROI, each physical descriptor corresponding to one or more of the actual features of a given physical object in the ROI; and storing the at least one physical descriptor in the ROI database. - View Dependent Claims (17, 18, 19)

20. A tangible, non-transitory computer readable recording medium recorded with a program that, when executed by a processor, causes the processor to implement a method for automated retrieval of images from an unstructured repository, the method comprising:
-
automatically locating images for analysis within the repository; populating a region of interest (ROI) database with the located images, the ROI database containing searchable entries representing images stored in the repository; segmenting the located images into a plurality of regions of interest (ROIs), each ROI containing content associated with one or more actual features of a physical object; extracting at least one physical descriptor from the content for each ROI, each physical descriptor corresponding to one or more of the actual features of a given physical object in the ROI; and storing the at least one physical descriptor in the ROI database. - View Dependent Claims (21, 22, 23)
