摘要： PROBLEM TO BE SOLVED: To provide an image identifying method and device capable of eliminating or extracting only a desired image from original images by paying attention to luminance information. SOLUTION: A means 200 binarizes and extracts all the images in the original images 190 and the means 300 extracts picture elements whose luminance is equal to or more than (or less than) a prescribed threshold value from the original images. For the threshold value, the value at the outside of the range of the luminance of the picture elements for constituting noise and in the inside of the range of the luminance of the picture elements for constituting an object image is set. By setting the threshold value in such a manner, at least a part of the object image is extracted without extracting the noise. In this case, instead of the luminance, the second order differential value of the luminance can be used as well. Thereafter, the means 400 obtains the image for covering the image of the object image extracted by the means 200 by expanding the image extracted by the means 300. Further, the image and the other image obtained by the means 200 are made a logical product. Thus, only the desired object image is accurately restored.

摘要： PROBLEM TO BE SOLVED: To obtain observation data matched with a flying date of remote- sensing data by providing a flow cell type bacteria measuring means, a bacteria evaluation formula forming means calculating bacteria distribution, a means calculating bacteria distribution in lakes and marshes and a data base. SOLUTION: The data measured by a bacteria measuring means 100 is regarded as the data of ground truth being a real value in lakes and marshes 10. Observation data is transmitted to a data base 700 to be stored. The observation data stored in the base 700 is used in the formation of a bacteria evaluation formula along with remote-sensing data in an evaluation formula forming means 300. A statistical analyzing technique is used to form the bacteria evaluation formula in the means 300. Further, the remote-sensing data stored in the base 700 is used in a bacteria distribution evaluation means 500 to calculate the bacteria evaluation formula to calculate the bacteria distribution in the lakes and marshes 10.

摘要： PROBLEM TO BE SOLVED: To reduce the time delay to offer the information in an urgent disaster mode by offering the risk information with an omen of disaster defined as a trigger. SOLUTION: When an omen of earthquake is detected, a data extraction means 150 evaluates the measurement value of the seismic intensity and the SI value (vibration intensity) and extracts the information on the areas where the damage is estimated out of a database 120. A thema chart generation means 200 automatically generates a thema chart where the extracted information is buried into the digital map information on the corresponding area and outputs a list of generated thema charts to a display standby list generation means 250. the means 250 generates a display standby list showing the order of display priority based on the damage level of the corresponding area, etc. The display standby list is dynamically reflected on the display menu of a risk information management system 100. Then the thema chart included in the display standby list is shown on a CRT 55 by an instruction given from an input device such as a keyboard 60, etc.

摘要： PURPOSE:To perform injection of a chemical correspondent to water quality value even in water quality at an unordinary time by predicting the quality of introduced water by fuzzy inference on the basis of the inferential rule relating to the change in water quality value of both the vicinity of the inlet of a water treating process and a remote place, turbidity, alkalinity, pH and flow rate value of raw water. CONSTITUTION:The signal of water quality value in the inlet part 20 of a channel well 10 is sent to an arithmetic circuit 23. On the other hand, the signal of water quality value of a remote place 21 is transmitted to a supervisory center 22 by a telemeter or the like. The water quality value sent to the supervisory center 22 is inputted to the arithmetic circuit 23 and compared with the water quality value of the inlet part 20 of the channel well 10 and calculated. The quality value of water introduced into the channel well 10 is conjectured in a fuzzy inferential circuit 24 on the basis of an inferential rule relating to fluctuation of the water quality value previously housed on a memory divide. The signal of the conjectured value is inputted to a sequencer 25. The signal of set value of a chemical injecting rate based on the predicted value of water quality is output to a chemical injecting device 26 from the sequencer 25. Chemical is injected into the channel well 10 or a rapidly admixing pond 11 from the device 26.
