摘要:
When a dispersion value of a shading value is equal to or more than a threshold value in the neighborhood of a standard point, it is determined that an image pattern has a texture dominant characteristic. When the value is less than the threshold value, a change of the shading value is determined to be moderate (S11). When the dispersion value is equal to or more than the threshold value (S11), a texture characteristic amount is loaded (S12), a characteristic amount suitable for area growth (e.g., texture energy) is calculated (S13), and a distance DT concerning the texture characteristic amount is obtained (S14). When the dispersion value is less than the threshold value (S11), a color component characteristic amount is loaded (S16), a characteristic amount suitable for the area growth (e.g., a characteristic vector obtained from a local histogram concerning a color component or a list of representative color components) is extracted (S17), and a distance DC concerning the color component is obtained (S18). The area is grown based on the corresponding characteristic amount (S15, S19), and a renewal position is determined based on a new borderline of a core area obtained by unifying area growth results from standard points (S20).
摘要:
A method and an apparatus for managing data including images, voice, characters, and the like, in a unified manner. The apparatus has an attribute file or an attribute table for registering therein an attribute peculiar to the data to be registered so that the data attribute can be registered simultaneously with the registration of the data. The data can thus be managed through an application in a unified manner based on the attribute data registered in the attribute file or the attribute table. In order to complete the processing of the application, the attribute data of the attribute file or the attribute table is set to be a mode either of "read-only" or "hidden".
摘要:
A file retrieval apparatus and method for retrieving a desired file out of a plurality of files stored in a storage medium. Retrieval is made based on the files, information on correspondence between the files and keywords, and attribute information of the keywords, to find a file that corresponds to an input keyword. When displaying the retrieved results in form of a list, a file a user most desires is displayed at the top of the list, and keywords located at lower levels of hierarchical keywords are also displayed as retrieval objects.
摘要:
A control system comprises a plurality of peripheral devices represented as objects, and a controller connectable to the plurality of peripheral devices via a common communication line for unitarily controlling the plurality of peripheral devices. The controller is arranged to be connected to an arbitrary number of peripheral devices selected from among the plurality of peripheral devices, read control information stored in the arbitrary number of peripheral devices via the communication line into a predetermined memory area of the controller in a predetermined format so that the controller can control the arbitrary number of peripheral devices. The controller is also arranged to issue a command and transmit the command to each of the arbitrary number of peripheral devices via the communication line.
摘要:
There are disclosed a method and system for managing a file that allows an operator to easily select, specify, and manage a multimedia file (including audio data, text, still image, moving image, etc.) via a display screen. The type of a file is identified. If the file is an audio data file, then an icon is generated with an image representing an amplitude waveform or a frequency distribution waveform of the audio data, or, the icon is generated with an image including a color or a pattern preassigned to the frequency distribution or both. If the file is a text file, then an icon is generated with an image representing an arbitrary area of an arbitrary page of the text file. If the file is a still image file, then an icon is generated with an image obtained by reducing an arbitrary area of the still image. If the file is a moving image file, then an icon is generated with an image obtained by reducing an arbitrary area of an arbitrary scene of the moving image.
