Abstract: A method for detecting motion pixels in image includes the following steps. The difference image between current image and background image is firstly obtained. Then, a binarization threshold from the distribution of all absolute pixel values in the difference image is found. All or part of the pixel values, in difference image, whose absolute values are smaller than or equal to the binarization threshold is used to compensate the effect of illumination change and to obtain an updated difference image. The updated difference image is then binarized, and the binarized updated difference image whose values are high are determined motion pixels.

Abstract: The image-based container defects detector consists of a plurality of camera units, a sensor unit, a frame grabber, and an image recognizer unit. The sensor unit serves to detect the vehicles entering the inspection station, and transmit a signal to the frame grabber for capturing the vehicle image by triggering the CCD camera thereby obtaining the information about the container's defect position and size. By dexterously utilizing image processing technique, the HIS (hue, saturation and intensity) color is employed to distinguish a normal area from a defected area in the container. Then quad-tree and merge is used to segregate image roughly. As for the non-defected area becoming obscured due to noise is removed using a filter. Finally the defected area is displayed on the screen. The present invention is well-suited for after detection as well as for on-line immediate detection for defect containers.

Abstract: An automatic car toll paying method is provided. Before a car enters a toll road or bridge, the user previously calls a specific number representing a log in of an automatic charging through a on-vehicle cellular communication equipment and then hangs up, and after leaving the toll road, the user calls a specific number representing a log out of the automatic charging. Continuously, wherein said on-vehicle cellular communication equipment has been logged in automatic charging when said car enters cell governing area of a communication coverage covering a toll station, the cellular base station will inform the billing center to automatically chargeback from an account connected to the on-vehicle cellular communication equipment or record the toll of the passing car.

Abstract: An automatic toll collection architecture and method combining short-range and long-range communication schemes comprising a vehicle communication unit, a lane communication unit, a law-enforcement unit and a billing unit; said law-enforcement unit obtaining a first time and a first photo of a license plate of said vehicle; said lane communication unit recording a first coordinate and a second time of a vehicle communication unit as a first data, using said vehicle communication unit to transmit said first data to said billing unit; said law-enforcement unit obtaining a third time and a second photo of said license plate of said vehicle; said lane communication unit recording a second coordinate and a fourth time of said vehicle communication unit as a second data, using said vehicle communication unit to transmit said second data to said billing unit; said billing unit obtaining a fee and finishing a charging transaction.

Abstract: An automatic car toll computing and charging method is provided. The method includes steps of employing a cellular phone to process a log in and a log out of a car toll computing; previously storing the connection between a cellular phone number and a vehicle identification number, or keying in said vehicle identification number or other car IDs sufficient to bring out said vehicle identification number in a billing center; and calling a specific number representing a log in of an automatic computing and charging through an on-vehicle cellular communication equipment and before a car enters a toll road or bridge and hanging up, and calling a specific number representing a log out of the automatic computing and charging after leaving the toll road or bridge. Consequently, the toll can be charged through calculating all cell IDs which by a cellular phone system passes theretrough during the log in and the log out.

Abstract: A digital image monitoring system with functions of motion detection and auto iris which aims at the requirement of video-recording monitoring for traffic facilities, home or company which is composed of CCD camera, lens, frame grabber, illumination—reflectance decomposition unit, illumination variation detection unit and motion detection unit. The frame grabber accompanies with the CCD camera and lens to take digital images continuously. Then the illumination—reflectance decomposition unit decomposes the captured digital image and transfers it into the illumination and reflectance spectrum to provide the illumination detection unit to analyze the illumination spectrum variation between two adjacent image frames and thus this spectrum variation is used to control the amplification or reduction of the iris; beside ,an object movement detection unit is provided to analyze the illumination variation of two adjacent films to judge if the object in the frame is moving .

Abstract: A structure for an infrared ray communication device placed over a lane which encloses a wireless infrared communication device and includes an upper cover for an attachment lens, an attachment lens, a rain shield, a light guiding device, a fixed support for an emitting module, a fixed support for a receiving module, a circuit board socket, a trough for a transformer, fixed hooks, and a rain shield. The device is placed over a path of a passing vehicle, and used to receive infrared rays and to proceed with data transmission.

Abstract: A realtime generating system for generating printed Chinese characters with multifonts and multiresolutions, includes a Chinese character compression sub-system and a printed Chinese character realtime generating sub-system. The former sub-system is used to compress the dot matrix characters into a character vector, and to store the character vector in the ROM (read only memory) of the latter sub-system. The compressed character vector is retrieved from the ROM and converted into a character outline in accordance with a Chinese character code and the specific resolution. The character outline is then processed through the steps of enlarging or shrinking, and filling to form a printed Chinese character.

Abstract: An apparatus for translating oracle-bone scripture style characters into formal style characters, and for translating formal style characters into oracle-bone scripture style characters includes a scanner for scanning printed characters and for providing a digital representation of the thus scanned printer characters. The printed characters are one of either the oracle-bone scripture style characters or the formal style characters. An oracle-bone scripture style and formal style character stroke feature analysis and learning unit is provided for extracting a feature of each scanned printed character, and for storing into an oracle-bone scripture style and formal style feature space storage device the thus extracted features of each scanned printed character according to a learning and analysis process.
