1. An apparatus for measuring gobs of viscous liquid in free fall from a gob feeder, comprising: means for capturing a complete two dimensional, frozen video image of a plurality of gobs at a point in time during free fall, wherein said frozen image is acquired via a single operation of said means for capturing; means for digitizing said video image to produce a first digitized image of at least a first gob of said plurality of gobs with n x n pixel arrays for comparison with a second digitized image of a second gob with n x n pixel arrays; and an image analyzing means for analyzing at least said first digitized image for relatively comparing said first digitized image with said second digitized image for determining any physical differences between said first and second gobs represented by said digitized images.
