This paper proposes a solution to the background segmentation and extraction in traffic video detection system. Weighted average method, Bimodal method and Median filter are employed to preprocess the video in the proposed solution. The preprocessing provides the satisfied precondition for the backgroud extraction. Furthermore, Gaussian Mixture Model is(More)
Airborne Light Detection and Ranging (LiDAR) topographic data provide highly accurate digital terrain information, which is used widely in applications like creating flood insurance rate maps, forest and tree studies, coastal change mapping, soil and landscape classification, 3D urban modeling, river bank management, agricultural crop studies, etc. In this(More)
