摘要： IMAGES ARE CLASSIFIED BY DIVIDING AN IMAGE INTO ELEMENTS. EACH ELEMENT IS ASSOCIATED WITH A PHOTOCELL, AND PHOTOCELLS ARE GROUPED IN EVEN NUMBERS COMPARISON HALF OF THE PHOTOCELLS PRODUCING A POSITIVE OUTPUT, AND HALF PRODUCING A NEGATIVE OUTPUT FOR THE SME ILLUMINATION CHARACTERISTIC. OUTPUTS OF CELLS IN THE GROUP ARE COMBINED AND COMPARED WITH OUTPUTS OF THE SAME GROUPS FOR DIFFERENT IMAGES IN KNOWN CLASSES. HIGHEST COMPARISON ABOVE A PREDETERMINED LEVEL DETERMINES CLASSIFICATION.

摘要： 1,208,126. Pattern recognition. SOC. ALSACIENNE DE CONSTRUCTIONS ATOMIQUES DE TELECOMMUNICATIONS ET D'ELECTRONIQUE. 24 Nov., 1967 [30 Nov., 1966], No. 53540/67. Heading G4R. An image is classified using the products of components of a vector representing the image with corresponding components of a reference vector obtained and stored during a previous learning mode. The array of photo-cells is divided into groups of photocells each group having say six photo-cells. A series of such groups are selected in turn under control of a store. For each group the difference between the sum of the outputs of half the photo-cells in the group and the sum of the outputs of the other half is digitized to + 1, - 1 or 0 by two thresholds to form one component of a vector specifying the pattern. During learning the above is done for a plurality of examples of each pattern, corresponding components of the vectors for a given pattern being added. Any components of the vectors thus obtained which are the same for all the patterns are eliminated, and may be replaced by components obtained from yet more groups of photo-cells, and if the resulting vectors are not approximately equal in length they are made so by using more examples of a pattern or multiplying all components of some vectors by a scalar. The finally resulting vectors are held in the store. During recognition, a vector is obtained for the unknown pattern as above and the scalar product of it with each of the stored vectors in turn is obtained. The largest scalar product identifies the pattern if it exceeds a threshold. Otherwise a fail-torecognize indication is given.

摘要： 1,203,260. Optical anlysis device. SOC. ALSACIENNE DE CONSTRUCTIONS ATOMIQUES DE TELECOMMUNICATIONS ET D'ELECTRONIQUE "ALCATEL". Nov.23, 1967 [Nov.25, 1966], No.53340/67. Heading G2J. In an image examination device, a bundle of single or stranded glass fibres transmits light from a source to a document or image being studied, there being, immediately above the document, a rigid block composed of single or stranded glass fibres bonded parallel to one another and pependicular to an optically polished lower face thereof, which block may be separate from or part of the bundle and correspondlingly is separate from or part of a second similar bundle, the upper ends of the fibres of which are connected to photo-sensitive cells. In one embodiment, Fig. 1, bundles of transmitting glass fibre conductors 2, from a source 3 are placed near, and at 45 degrees to the top face of a rigid block 6 of short glass fibres which transmit light to a document 1 and retransmit light which is focussed by an objective 7 on the bottom of a block 5 of receiving glass fibres, the other ends of which are connected to photo-cells (not shown). The objective may be focused be using a sighting system Fig. 2 (not shown) comprising a retractable mirror (8) an eye-piece (9) and a graticule sight (10). In another embodiment Fig, 3 (not shown) a document is mounted on a carrier stage (13) and light from a source is transmitted to the document through flexible light conductors (17) and a honeycomb block (15) in contact with the document. Light travels back through the honeycomb block and is focused by an objective (18) on the optically polished square bottom of a block (19) of 225 receiving light conductors, the other ends of these conductors being connected to photo-cells. An image adjustment device, similar to that of the first embodiment, is included.
