What libraries are there for QR code recognition on vb.net?

Question

.NET

I use the QR code recognition library - ZXing, ported to vb. Used to recognize a QR code on a document scan.
Now about 10% of the recognized files are not recognized. Can you suggest alternative options for recognition?
UPD: a QR code is being recognized from a scan of documents. Scanning occurs in the best quality at 300-400 dpi. The document has a resolution of 3307x4677. The QR code contains information about the counterparty.
Now I'm working with the ZXing.net 0.16.4 package. Downloaded from NuGet.
Also, if the entire scan is not recognized, then the image is divided into 15 elements and each element is separately tested. This separated element tried to increase, the result was not followed.
I recognize the method MultiFormatReader.
As a result, after trial and error, I found out that the BarcodeReader class works better than MultiFormatReader, but you need to specify the parameters:

TryHarder = True 
Rotate = True.

Answer 1

ZXing is a great library, maybe worth a try:
1. Use a version of the barcode with a higher level of error correction
2. Use a different type of barcode
3. Enlarge the image of the barcode
4. Add an additional barcode
, etc.
