IMAGE BASED OBJECT LOCATOR

摘要

Techniques, systems, and devices are disclosed for analyzing a reconstructed charged particle image of a volume of interest from charged particle detector measurements to determine a location and boundaries of one or more objects or an orientation of the one or more objects. The technique can include performing a segmentation operation on the reconstructed charged particle image of the volume. The segmentation operation identifies a subset of a set of voxels of the image of the volume as object candidate voxels. The technique can include locating corners of the one or more objects to determine the location, boundaries, or the orientation of the one or more objects. The technique can also include the computation of the center of mass of the one or more objects. The technique can include performing a morphological operation on the image and can include performing a connected-component analysis on the identified object-candidate voxels.

1. A method for analyzing a reconstructed charged particle image of a volume from charged particle detector measurements to determine a location and boundaries of one or more objects associated with the volume, the method comprising:
performing a segmentation operation on the reconstructed charged particle image of the volume, wherein the segmentation operation identifies a subset of a set of voxels of the reconstructed charged particle image of the volume as object candidate voxels; and determine the location, boundaries and corners of the one or more objects.
