Unsolved QZXing can't decode some vague images.

[Zhangs]

Hi all,
I am using QZXing on Android to do qrcode scan.
But for some vague images, it can't decode.
Most apps(Tecent Weixin etc.) can decode it.
Could anyone help me to solve this issue?
Thank you very much!

@Zhangs Did you ask the project alread (https://www.kdab.com/efficient-barcode-scanning-qzxing/)?
QZXing isn't part of Qt.
