A recognition apparatus is provided with a plurality of recognition units organized in a multilayered hierarchical structure. Each of the recognition units includes a signal input section, a quantizer for performing a quantization according to a signal inputted from the signal input section, and a path selecting section for performing a selection of paths according to an output from the quantizer. The path selecting section includes a path input section having at least one path input terminal, a...

A matrix array of objects, for example, semiconductor bars, is located on a carrier such as an XY table and the objects are successively brought into the field of view of a television camera to produce digitized video signals which are utilized in effecting precise alignment of the object with respect to a reference point. Following this alignment step, an electronic analysis is made, again on the basis of digitized video signals, to confirm the presence of an object in the aligned position, and...

A recognition system comprising a transmitter for radiating an amplitude modulated signal to a target that generates a harmonic of the received signal, detects the amplitude modulating signal and modulates the harmonic signal with the detected signal. The target contains a frequency selective network that produces a coded arrangement of signal components which comprise the signal returned by the target. A receiver detects the coded arrangement of signal components.

An optical apparatus and method for recognition of three-dimensional objects comprising an uneven illumination to project a striated pattern of illuminated and non-illuminated areas on the object which is scanned along a plurality of successive scan lines for generating video data which is compared with reference data for object recognition purposes.

A recognition apparatus of this invention for recognizing sorting information as a character string written within a cellophane region of a paper-like material extracts edge components according to a differential image based on an image of light and shade of the paper-like material, determines a cellophane frame based on the edge components and recognizes the character string within the thus determined cellophane frame as an address. Thus, the cellophane region in which the address used as the s...

A line recognition adapted for recognizing a drawing in which a plurality of lines overlapping one another are indicated by a given one of the mutually overlapping lines and overlap symbols representative of the other lines. The overlap symbols are so configured as to give information as to line kinds of the other lines such as solid line, dash line and chain line and/or information as to colors of the other lines. The paths of the other lines are estimated on the basis of the overlap symbols as...

An object recognition system includes several pivotable cameras and frame stores for capturing images of the moving object from various aspects. The data is passed to compressors to provide simplified correlation of data in correlators also receiving data from a compressed image library to allow the object and/or its orientation to be determined.

In image recognition systems of the type employing a frame store having groups (N-tuples) of locations mapped to storage forming discriminators trained, or capable of being trained, to respond to different images, a problem arises in that either a large number of separate discriminator stores are required or recognition times are long. In the present invention the discriminator storage comprises p discrete stores having address terminals divided into two groups: one group directly mapped to resp...

This invention relates to character recognition and more particularly to a method of editing a document prior to optical scanning thereof in a character recognition system.

System operating regimes are identified by dividing a range of each one of a plurality of sensed system parameters into a plurality of predetermined range segments, assigning an alphanumeric character to each range segment of each parameter, and generating a composite number, each digit of which is made up of one of the alphanumeric range segment characters of each parameter. Apparatus compares the current sensed values of each parameter to the corresponding predetermined range segments to deter...
