A topological transformation system for transforming and extracting data from distributed images in n-dimensional spaces. The system is disclosed in two-dimensional form as principally comprising an iterative array of logical cells, each of which may be used to contain duplicates of each element of the distributed image. The duplicates are translatable with respect to each other simultaneously in all possible directions, and comparisons may be made at each translational step between the current image and previous or transformed versions of the image. An example is described for deriving the center points of holes in a two-dimensional image, and a four-dimensional iterative array is also disclosed.

Topological transformation system

A method and related apparatus for finding center lines or center points of distinguishable areas in a scanned field, such as the field of view of an optical scanning device in which is positioned an integrated-circuit chip. The invention is disclosed in the form of circuitry for analyzing a serial digital data stream representative of the image of the scanned field, and for determining the positions of center lines of center points of distinguishable areas in the field falling within a selected size range. The circuitry includes separate sections for analyzing the scanned image in order to detect center lines with respect to four separate scanning directions, the outputs of these sections being synchronized with each other, although delayed from the original serial data stream, and being representative of center lines of areas falling within the selected size range. The outputs of the four separate sections may be logically combined in any desired manner to produce a serial output signal indicative of center points of areas falling within the selected size range. Selected center points may then be used in conjunction with a wire bonding machine to provide information indicative of the position and orientation of the chip.
