      • detect

        public boolean detect​(Mat img,
                      Mat points)
        Detects Barcode in image and returns the rectangle(s) containing the code.
        Parameters:
        img - grayscale or color (BGR) image containing (or not) Barcode.
        points - Output vector of vector of vertices of the minimum-area rotated rectangle containing the codes. For N detected barcodes, the dimensions of this array should be [N][4]. Order of four points in vector< Point2f> is bottomLeft, topLeft, topRight, bottomRight.
        Returns:
        automatically generated

      • decode

        public boolean decode​(Mat img,
                      Mat points,
                      java.util.List<java.lang.String> decoded_info,
                      java.util.List<java.lang.Integer> decoded_type)
        Decodes barcode in image once it's found by the detect() method.
        Parameters:
        img - grayscale or color (BGR) image containing bar code.
        points - vector of rotated rectangle vertices found by detect() method (or some other algorithm). For N detected barcodes, the dimensions of this array should be [N][4]. Order of four points in vector<Point2f> is bottomLeft, topLeft, topRight, bottomRight.
        decoded_info - UTF8-encoded output vector of string or empty vector of string if the codes cannot be decoded.
        decoded_type - vector of BarcodeType, specifies the type of these barcodes
        Returns:
        automatically generated

                               Mat points)
        Both detects and decodes barcode
        Parameters:
        img - grayscale or color (BGR) image containing barcode.
        decoded_info - UTF8-encoded output vector of string(s) or empty vector of string if the codes cannot be decoded.
        decoded_type - vector of BarcodeType, specifies the type of these barcodes
        points - optional output vector of vertices of the found barcode rectangle. Will be empty if not found.
        Returns:
        automatically generated
