  • Detection of agricultural contraband in baggage
    Patent number: 4539648
    Abstract: A radiant energy imaging system for selectively enhancing the image of objects having circular cross section to distinguish them from the image of objects having rectangular cross section, such objects being contained in a material having a different density-absorption coefficient product than the objects. In the invention, the gradient image of the spatially resolved transmitted intensity of the radiation is calculated and eroded to preferentially remove the edges of images of objects having rectangular cross section. The invention finds particular use in detecting agricultural contraband contained in baggage or parcels.
