Patent Images

1. A method for measuring arc length along a boundary in an image including a plurality of pixels, the method comprising the steps of:

  • providing an image processor programmed to perform the steps of;

    determining an arc position for each boundary point along a segment of the boundary, starting with zero at a first boundary point at a first end of the segment, and increasing while moving away from the first end by an amount equal to the distance between the boundary points along the segment; and

    determining total arc length of the segment as being the arc position of a boundary point most distal from the first boundary point of the segment.
