  • Three-dimensional object image generation
    Patent number: 11436735
    Abstract: A volume of an object is extracted from a three-dimensional image to generate a three-dimensional object image, where the three-dimensional object image represents the object but little to no other aspects of the three-dimensional image. The three-dimensional image is yielded from an examination in which the object, such as a suitcase, is situated within a volume, such as a luggage bin, that may contain other aspects or objects that are not of interest, such as sidewalls of the luggage bin. The three-dimensional image is projected to generate a two-dimensional image, and a two-dimensional boundary of the object is defined, where the two-dimensional boundary excludes or cuts off at least some of the uninteresting aspects. In some embodiments, the two-dimensional boundary is reprojected over the three-dimensional image to generate a three-dimensional boundary, and voxels comprised within the three-dimensional boundary are extracted to generate the three-dimensional object image.
