Package org.opencv.objdetect

  • Class Summary 
    Class Description
    ArucoDetector
    The main functionality of ArucoDetector class is detection of markers in an image with detectMarkers() method.
    BarcodeDetector  
    BaseCascadeClassifier  
    Board
    Board of ArUco markers A board is a set of markers in the 3D space with a common coordinate system.
    CascadeClassifier
    Cascade classifier class for object detection.
    CharucoBoard
    ChArUco board is a planar chessboard where the markers are placed inside the white squares of a chessboard.
    CharucoDetector  
    CharucoParameters  
    DetectorParameters
    struct DetectorParameters is used by ArucoDetector
    Dictionary
    Dictionary/Set of markers, it contains the inner codification BytesList contains the marker codewords where: - bytesList.rows is the dictionary size - each marker is encoded using nbytes = ceil(markerSize*markerSize/8.) - each row contains all 4 rotations of the marker, so its length is 4*nbytes bytesList.ptr(i)[k*nbytes + j] is then the j-th byte of i-th marker, in its k-th rotation.
