A feature extracting method converts an image data of an input line drawing into a graph representation and recognizes the input line drawing by use of the graph representation. The feature extracting method comprises a first step of equally dividing the image data of the input line drawing into meshes, a second step of obtaining a cell by integrating one or more meshes, and a third step of recognizing a cell pattern for each of cells which are obtained so as to form a graph in correspondence with each of the cells.

A robot control apparatus including a first coordinate transformation unit for transforming an output from a setting unit for setting moving positions of a robot into information in a predetermined general coordinate system. A selector changes the destinations of output information from the first coordinate transformation unit dependent on the type of robot being controlled. A second coordinate transformation unit is provided having a plurality of transformation sections for transforming outputs in the general coordinate system from the first cooridnate transformation unit into information in a coordinate system inherent to the particular robot. The output from the first coordinate transformation unit is applied to one of the transformation sections which is selected by the selector. Robot drive signals are produced in response to output information from the second coordinate transformation unit.

A robot controller including a movement command forming unit, object position variable forming unit, a compressing/enlarging unit, a plurality of position control units, and an object position command unit. The movement command forming unit specifies the formation of a plurality of movement object positions. The object position variable forming unit forms a position variable used to correct a position deviation from a previously taught position or a manually entered position. The compressing/enlarging unit operates to compress or enlarge object position variables outputted by the object position variable forming unit. The position control unit receives respective object position variables to perform velocity control and position control. The object position command unit adds the output signals of the position control units to output an object position command, according to which the robot is moved to the object position.

Disclosed is an extraction method for optical character recognition systems in which the necessary character features for recognition process are extracted from a character information detected and digitized by an optical scanner. In accordance with this method, the local features of every adjacent two rows or columns of a digitized character pattern on a two-dimensional plane are extracted row by row or column by column and are successively integrated so as to extract in a global manner the respective feature types such as concavity and convexity, loop and connectivity of the character pattern. At the same time, the global feature regions or segments are separated and each of the separated feature segments is coded without any loss of the information. The feature quantity of each segment is obtained on the basis of the coded representation. Any local concavity or convexity noises are eliminated simultaneously with the extraction of the global features.

An arc welding robot control system in which a control console stores the welding conditions upon the completion of a welding cycle. When a suspension of the welding cycle is commanded during its execution, the welding cycle is effected under the stored welding conditions and its robot is stopped at a suspension point. The control console may further include two memories for respectively storing the position of the suspension point and a current and the next position of the robot with coefficients for a linear interpolation. When the welding cycle is restarted after the robot has been displaced from the suspension point to another point, the torch is automatically returned back to the suspension point along a line passed through the two points and points interpolated through calculations of the content of the memories. The torch is moved through taught points and a similarly interpolated point.

A method is provided that includes capturing an input handwritten character with parameter representation for each stroke and applying a polygonal approximation thereto; assuming each polygonal line segment approximated to be vector that reaches an end point from a start point, and obtaining an angle between an axis that becomes a reference and each line segment as a polygonal line segment angle sequence; obtaining an exterior angle sequence of vertices of the line segments; making a sum of exterior angles of the same sign, where the same sign of plus or minus in the exterior angle sequence continues, to be a winding angle sequence; extracting a global feature according to each obtained sequence and a localized or quasi-localized feature in each curved portion divided corresponding to the winding angle sequence, hierarchically and divisionally; and performing character recognition by comparing the extracted result with a template of an object character.

A processing terminal 10 includes a writing implement (ball point pen) 30. The writing implement 30 is provided with a tilt change detecting mechanism for detecting a change in a tilt with respect to a writing implement main body of a lead and a vibration detecting mechanism for detecting the change in the vibration of the vibrated lead at the time of handwriting. The processing terminal 10 produces handwriting motion information based on both of the detected changes in the tilt of the lead and in the vibration. A handwriting identification organization 20 compares handwriting motion information with inherent information stored previously to identify handwriting. Thereby it can achieve high reliability in an authentication system with a simple structure.

The fluidizing speed of water inside a flocculation basin of a water treatment process plant is adjusted in accordance with the state of flocculation inside the flocculation basin. The state of flocculation is determined by taking a plurality of pictures within a predetermined period by an ITV disposed inside the basin, recognizing a sufficiently large number of flocs from the pictures thus taken, calculating the particle diameters of the flocs and determining the particle diameter distribution from the result of calculation. The judgement signal is used as a signal for adjusting the water fluidizing speed.

A system for controlling a process utilizing filamentous microorganisms is disclosed. The amount of the microorganisms in a medium for growing the filamentous microorganisms is measured, and the control factors associated with the growth of the microorganisms in the medium are controlled on the basis of the measurement of the amount of microorganisms. In the process of measuring the amount of microorganisms, an optical image of a specimen of the medium is formed and scanned two-dimensionally to produce a series of brightness signals corresponding to the brightness distribution of the optical image. The level of the brightness signal is used to determine the amount of the microorganisms contained in the medium.
