Gregory P Weeks, Akhileswar G Vaidyanathan, Michael J Merrill: Method for determining quality of dispersion of glass fibers in a thermoplastic resin preform layer and preform layer characterized thereby. E I Du Pont de Nemours and Company, July 25, 1995: US05436980 (28 worldwide citation)

A method for determining the quality of dispersion of glass fibers in a thermoplastic resin preform layer compares the mean characteristic length of the glass fiber bundles in the preform layer to a predetermined value indicative of dispersion of the glass fibers. The thermoplastic resin preform lay ...

Akhileswar G Vaidyanathan, Hooshmand M Kalayeh: Methods for determining the exterior points of an object in a background. E I Du Pont de Nemours and Company, November 26, 1996: US05579409 (16 worldwide citation)

Accessing the exterior points of an object is used in the area of object identification when it is important to use the information in the local exterior environment of an object in order to extract a feature which may be useful for object recognition. Examples of this type of feature which are impo ...

Akhileswar G Vaidyanathan: Method of determining the interior points of an object in a background. E I Du Pont de Nemours and Company, Jane E Obee, December 6, 1994: US05371810 (16 worldwide citation)

The present invention relates to an image analysis method for determining the interior points of an object in a background when the contour, or perimeter points, of the object are known. By accessing the interior points of an object, textural and color information can be derived, thereby allowing fo ...
