    Patent number: 4637054
    Abstract: The condition of an article e.g. a multihead tool array is compared after having been subjected to some operation with its previous condition e.g. before and after a drilling or other operation of the tool array by forming an image, e.g. a video image, of the article before the operation and automatically comparing it with a second such image formed after the operation. Known image enhancement techniques can be used, and statistical techniques used in data processing equipment to detect significant differences between the images.
