Syntax

public class WeChatQRCode : DisposableCvObject, ICvPtrHolder

Methods

Create(String, String, String, String)

Initialize the WeChatQRCode. It includes two models, which are packaged with caffe format. Therefore, there are prototxt and caffe models (In total, four paramenters).

Declaration

public static WeChatQRCode Create(string detectorPrototxtPath, string detectorCaffeModelPath, string superResolutionPrototxtPath, string superResolutionCaffeModelPath)

Parameters

Type	Name	Description
System.String	detectorPrototxtPath	prototxt file path for the detector
System.String	detectorCaffeModelPath	caffe model file path for the detector
System.String	superResolutionPrototxtPath	prototxt file path for the super resolution model
System.String	superResolutionCaffeModelPath	caffe file path for the super resolution model

Returns

Type	Description
WeChatQRCode

DetectAndDecode(InputArray, out Mat[], out String[])

Both detects and decodes QR code. To simplify the usage, there is a only API: detectAndDecode

Declaration

public void DetectAndDecode(InputArray inputImage, out Mat[] bbox, out string[] results)

Parameters

Type	Name	Description
InputArray	inputImage	supports grayscale or color(BGR) image.
Mat[]	bbox	optional output array of vertices of the found QR code quadrangle.Will be empty if not found.
System.String[]	results	list of decoded string.
