That demo shows the way of decoding barcodes from webcam image with the use of EmguCV. There are two ways to do that: * Use the default BarcodeReader from ZXing.Net which accepts a System.Drawing.Bitmap as the input (simplest way) * Write your own luminance source class which accepts the Image class from EmguCV (simple way) The demo shows the second one which needs a custom luminance source. The following class is needed * ImageLuminanceSource: calculating the luminance values based upon a Image The next two classes are nice to have but only needed to have clear class structure: * IBarcodeReaderImage: interface for the customized barcode reader * BarcodeReaderImage: barcode reader class which is derived from BarcodeReaderGeneric. It is needed for the ImageLuminanceSource instance which the BarcodeReaderGeneric consumes.
