Patent Images

1. A method of imaging an object comprising:

  • obtaining an image data set from a raster scan of the object, the image data set comprising a plurality of data points, each data point having a location and intensity associated with it;

    generating a reduced data set by selectively removing one or more data points from the image data set based upon an assigned probability of retaining the one or more data points in the data set, the assigned probability being a function of the intensity of a data point;

    generating a triangulation graph of the reduced data as a planar subdivision having faces that are triangles, the vertices of which are the data points of the reduced data set and the edges of which are adjacent vertices; and

    segmenting the triangulation graph by finding a path with lowest cost between vertices of the triangulation graph, wherein the cost between vertices is a function of the respective intensity of the vertices.
