—On the basic of the video traffic surveillance system, the Vehicle detection is a crucial step. A typical method is background subtraction. Extracting and updating the background plays an important role on speed and efficiency of detection. For this reason, the author puts forward a fast and effective method for building and updating the background model.(More)
—By means of Sequence Mean Method based on a series of consecutive video images to extract the background, this paper makes use of difference model of colored images to make difference on both images, hence to obtain effective goals of moving vehicles. As regard to post-treatment of the test results, it proposes an algorithm for real-time segmentation and(More)
In this paper, we describe a Non-Parametric Kernel (NPK) method for localization of mobile users in the indoor CDMA2000 environment. This method makes use of CDMA2000 reference pilot, pilot delays, and pilot signal strength measurements to build a mobile signal fingerprint map in a given indoor environment in the off-line stage, and uses this fingerprint(More)
