An object recognition system using the image processing in which an area having a unique feature is extracted from an input image of an object, the unique image is registered in a shade template memory circuit as a shade template, the input image is searched for an image similar to the shade template registered by a shade pattern matching circuit, the position of an object is determined for each template, the speed and direction of movement of the object is determined from the positional information, and the results thereof are integrated by a separation/integration circuit, thereby recognizing the whole of the moving object.

Object recognition system and abnormality detection system using image

In a graphic data processing system of a CAD system for the design of an LSI, there is provided a display screen, a storage in which graphic data structured in the hierarchy of three levels, i.e. a functional block diagram level, a logical symbol level and a circuit component level, and a pointing device for designating a window within the display screen. The display method of the present invention is characterized in that the size of a designated window is judged and the graphic data of the concept level corresponding to the judged size of the window is read out and displayed within the window.

Data display method

A natural language including Japanese, Korean, Chinese, etc., is suitably processed when an undefined word which is not registered in a dictionary appears in an input character train. When the undefined word appears, a semantic analysis processor decides a semantic concept of the undefined word by using a case dictionary. Further, by using a vocabulary hierarchy dictionary, which registers vocabularies in a hierarchy structure, the semantic analysis processor extracts a group of vocabularies (synonyms) corresponding to a lower concept of the semantic concept of the undefined word. The natural language processing can be achieved practically and efficiently with dictionaries of a limited storage capacity.

System for processing natural language including identifying grammatical

A method and apparatus of intelligent guidance in a natural language in which the user of an information terminal apparatus is only required to input the content of a job to be executed, in a natural language which is used in usual conversation, and not in the form of the so-called command train, and in which the terminal apparatus automatically analyzes and understands the inputted content, and displays a command train required to execute the job to the user, thus, even when the user not familiar with the manner of manipulating the information terminal manipulates the terminal, he can converse with the information terminal in the natural language.
