Abstract
A method for characterizing a fibrous material having a plurality of fibers is provided. The method includes accessing an image of the fibrous material with the plurality of fibers and identifying each of the plurality of fibers based upon a magnitude and a direction of an intensity gradient of the image. The method also includes tracking each of the identified fibers based upon at least one of a diameter of the fiber, a fiber alignment angle and a vector orientation angle of the fiber and estimating a plurality of structural parameters for each of the tracked fibers of the fibrous material.
