20100322518	IMAGE SEGMENTATION BY HIERARCHIAL AGGLOMERATION OF POLYGONS USING ECOLOGICAL STATISTICS - A method for rapid hierarchical image segmentation based on perceptually driven contour completion and scene statistics is disclosed. The method begins with an initial fine-scale segmentation of an image, such as obtained by perceptual completion of partial contours into polygonal regions using region-contour correspondences established by Delaunay triangulation of edge pixels as implemented in VISTA. The resulting polygons are analyzed with respect to their size and color/intensity distributions and the structural properties of their boundaries. Statistical estimates of granularity of size, similarity of color, texture, and saliency of intervening boundaries are computed and formulated into logical (Boolean) predicates. The combined satisfiability of these Boolean predicates by a pair of adjacent polygons at a given segmentation level qualifies them for merging into a larger polygon representing a coarser, larger-scale feature of the pixel image and collectively obtains the next level of polygonal segments in a hierarchy of fine-to-coarse segmentations. The iterative application of this process precipitates textured regions as polygons with highly convolved boundaries and helps distinguish them from objects which typically have more regular boundaries. The method yields a multiscale decomposition of an image into constituent features that enjoy a hierarchical relationship with features at finer and coarser scales. This provides a traversable graph structure from which feature content and context in terms of other features can be derived, aiding in automated image understanding tasks. The method disclosed is highly efficient and can be used to decompose and analyze large images.	12-23-2010

Additional preferred aspects of the present invention can include detecting non-pervasive changes between sets of images in response at least in part to one or more difference images between the sets of images.	06-20-2013

20100101956	NANOSCALE DNA DETECTION SYSTEM USING SPECIES-SPECIFIC AND/OR DISEASE- SPECIFIC PROBES FOR RAPID IDENTIFICATION - A method and system for detecting a DNA strand using carbon nanotubes or nanowires. A specific single strand of template DNA serves as a probe for its complementary strand in a solution containing DNA segments to be tested. The single-stranded sequence-specific DNA probe segment, whose ends are modified with amine, is attached between two carbon nanotubes/nanowires. When complementary strands representing DNA segments under test are brought near the probe strands, a dielectrophoresis (DEP) field may enhance the probability of selective hybridization between the complimentary target DNA and probe DNA. A change in electrical conductance in the probe strand occurs upon hybridization of the complementary target DNA with the single probe strand. This conductance change may be measured using the two carbon nanotubes or nano-dimensional electrodes. By exploiting nano-dimensional electrodes and single strand probe DNA, the proposed system is capable of accurately detecting a single molecule of DNA.	04-29-2010
