    Sammanfattning : This study investigates the performance of two keypoint detection algorithms, SIFTand LoFTR, for vehicle re-recognition on a 2+1 road in Täby, utilizing three differentmethods: proportion of matches, ”gates” based on the values of the features andSupport Vector Machines (SVM). Data was collected from four strategically placedcameras, with a subset of the data manually annotated and divided into training,validation, and testing sets to minimize overfitting and ensure generalization.

  3. 2. Recognition of Targets in Camera Networks

    Magister-uppsats, Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Författare :Fredrik Johansson; [2008]
    Nyckelord :;

    Sammanfattning : This thesis presents a re-recognition model for use in area camera network surveillance systems. The method relies on a mix of covariance matrix fea- ture descriptions and Bayesian networks for topological information. The system consists of an object recognition model and an re-recognition model. LÄS MER
