摘要： An image processing apparatus comprises a character extraction unit (12, 24) for extracting an area whose density distribution characteristic meets a predetermined condition such as a binarization threshold and a size and a type of local filtering, from an input image (11) of multiple gray levels, and extracts an object area (15a) as an output image - (13) from the input image by using the characteristic extraction unit. Area designation means (15, 25) designates an area having a uniform density distribution and containing the object area, to the input image. Condition determination means (16, 26) determines the condition for the characteristic extraction unit based on the density distribution characteristic of the input image in the designated area. In an image processing expert system, the image characteristics of the object image and the background in the area designated by the area designation means are evaluated and analyzed (227, 223, 224) and the inquiry in the form of message is effected to quantize the evaluation of the image characteristic. As a result, the area extraction procedure (222) can be easily executed by the interaciton with an operator.

摘要： In continuous sign language recognition, reference sign language patterns of good quality are generated. Continuous sign language patterns and reference sign language patterns are efficiently compressed. The compressed continuous sign language patterns are sequentially and directly matched with the compressed reference sign language patterns to recognize the sign language at high speed and with high precision. A reference sign pattern generating unit (3) generates a reference sign language pattern by normalizing sample patterns while taking into consideration of their nonlinear compression/expansion and by calculating an average of the sample patterns. A continuous sign language recognition unit (5) recognizes a continuous sign language at high speed by sequentially matching the continuous sign language of time sequential patterns with reference sign language patterns while allowing nonlinear expansion and compression in the time domain. A sign language translation system is provided in which a sign language as well as the facial expression or emotion of a sign language user is recognized and converted into a spoken language with emotion, and transferred in the form of texts, voices, sign languages of another type to a particular partner among a plurality of unknown system users.

摘要： An elevator car and a counterweight is suspended on a sheave by means of a rope in a well-rope faashion. In dependence on the number of passengers on the car, the sheave is applied with an unbalance torque making appearance between the car and counterweight. Upon starting of the elevator operation by releasing a brake, upward or backward bouncing of the car takes place due to the unbalance torque. For preventing such bouncing of the car, a start compensation is performed by generating a motor torque which can cancel out the unbalance torque in precedence to the releasing of the brake. The brake is installed swingably on a winding equipment. Displacement of the brake during actuation thereof indicates the presence of the unbalance torque. By taking advantage of this displacement, the start compensation is carried out by increasing the motor torque progressively in the direction depending on the displacement and by holding the motor torque constant at a value attained when the displacement becomes smaller than a predetermined value.

摘要： Elevator group supervisory control method and system for group supervisory control of a plurality of elevators serving a plurality of floors. The method and apparatus of the invention permits the inputting of qualitative requests (guidance), from the user, concerning elevator operation into the group supervisory control system. Qualitative requests concerning elevator operation are set in the form of guidance (or request) targets. The thus set request targets are converted into control targets for the elevators. Actual group supervisory control is executed using the control targets.
