News editors obtained the following quote from the background information supplied by the inventors: "Systems and methods for generating depth maps for images have suffered from lack of precision and requirements for great computing resources. Additionally, specialized hardware is often required in order to generate such a depth map. Imprecision in generation of such a depth map may result in poor resolution of acquired images and difficulty in identifying precise locations of objects within those depth maps. Without such precise identification of these locations, later processing of these images and objects may result in a reduced ability to rely on these locations and objects for additional processing.
"Therefore, it would be desirable to present a method and apparatus that overcomes the drawbacks of the prior art."
As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "In accordance with various embodiments of the present invention, a method and apparatus is provided for stabilizing segmentation and depth calculations. The inventors of the present invention have presented, in U.S. patent application Ser. Nos. 13/025,038, titled 'Method and Apparatus for Performing Segmentation of an Image', filed
"As is described in the '038, '055 and '070 applications, it is meaningful to look only at one or more changes associated with a given stereo image sequence to produce a subsequent depth map and not the entire image. Thus, rather than recomputing an entirely new depth map for each pair of stereo images over time, only changes between consecutive frames are computed and integrated into one composite depth map. This process is not only computationally more efficient than recomputing the complete depth map for each stereo frame pair, it is also more accurate for matching, since only regions with significant changes are being matched in any given frame or sequence of frames. This is an altogether novel approach to computational stereo as previous attempts have been faced with a significant amount of computational complexity, problems with limiting a candidate space of depth calculations, and a nebulous set of features at best to extract from, without these features being robust to significant changes in the scene's quality or even overall color scheme.
"In accordance with various embodiments of the present invention, a framework with which such an approach can be accomplished is provided, defining various types of regions and segments that are associated with such an approach. Also presented are other relevant aspects and features to develop a set of factors that can improve the accuracy of segmentation and the accuracy of the depth map itself, by presenting a shallow-depth of field concept with two different realizations.
"Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification and drawings.
"The invention accordingly comprises the several steps and the relation of one or more of such steps with respect to each of the other steps, and the apparatus embodying features of construction, combinations of elements and arrangement of parts that are adapted to affect such steps, all as exemplified in the following detailed disclosure, and the scope of the invention will be indicated in the claims."
