摘要： Fire detection and smoke detection use an image capturing device to obtain images from a predetermined area and adopt an RGB (red, green, blue) color model based chromatic and disorder measurement for extracting flame pixels and smoke pixels. The extracted pixels are inputted to a fire detection fuzzy alarm system to generate an output of alarm information. Based on iterative checking on the growing ratio of the alarm information, a fire alarm is released accordingly.

The method includes checking if the frame is vibrating and calculating a degree of vibration for compensating a vibration area. Based on block motion estimation, a feature block selected from nine fixed observation blocks is used to obtain a vibration vector. The vibration vector is used to adjust the vibration frame for restoring the frame.

摘要： Based on area and color analyses, a cost-effective bi-directional people counter dedicated to the pedestrian flow passing through a gate or a door is proposed. Firstly, the passing people are roughly counted with the area of people projected on an image captured by a zenithal video camera. The moving direction of the pedestrian can be recognized by tracking each people-pattern with an analysis of its HSI histogram. To improve the accuracy of counting, the color vector extracted from the quantized histograms of intensity or hue is introduced to refine the early counting. Besides, the inherent problems of both people touching together and merge/split phenomenon can be overcome.

摘要： A method and system for detecting early fires in a predetermined area includes capturing a plurality of images of the predetermined area during an interval for generating a plurality of difference frames, and detecting a number of pixels that have fire characteristics in each difference frame. If the detection result indicates that the flame of the predetermined area substantially increases during the interval, the method outputs an early fire alarm that can provide more time for firefighting. Thus, both early fire detection and reduction of false fire alarms are achieved.

摘要： While locating a license plate of a moving vehicle on consecutive images, motion detection is first performed on the consecutive images to detect a moving vehicle image, which is segmented using edge detection, and the segmented moving vehicle image is analyzed to retrieve characteristics for locating a license plate image and determining characters on the located license plate image. As a result, a precise location of the license plate is thus precisely located for further recognition no matter what weathers in which the consecutive images are recorded. The above-mentioned technique requires merely few calculations, is easily implemented, and may be applied on an intelligent digital video recording (DVR) system including many computer-vision functions.
