Constructor Detail

BarcodeDetector

protected BarcodeDetector(long addr)

BarcodeDetector

public BarcodeDetector(String prototxt_path,
                       String model_path)

Initialize the BarcodeDetector.

Parameters:

prototxt_path - prototxt file path for the super resolution model

model_path - model file path for the super resolution model

BarcodeDetector

public BarcodeDetector(String prototxt_path)

Initialize the BarcodeDetector.

Parameters:

prototxt_path - prototxt file path for the super resolution model

BarcodeDetector

public BarcodeDetector()

Initialize the BarcodeDetector.

Method Detail

getNativeObjAddr

public long getNativeObjAddr()

__fromPtr__

public static BarcodeDetector __fromPtr__(long addr)

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,
                      List<String> decoded_info,
                      List<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

detectAndDecode

public boolean detectAndDecode(Mat img,
                               List<String> decoded_info,
                               List<Integer> decoded_type,
                               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

detectAndDecode

public boolean detectAndDecode(Mat img,
                               List<String> decoded_info,
                               List<Integer> decoded_type)

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

Returns:

automatically generated

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable
