Since I am doing a research on aesthetic QRcode and I want to know how much that I distorted on the original QR code. zxing is a toolbox that can decode QRcode. After reading its documentation, I found that there exists com.google.zxing.qrcode.decoder.Decoder and it has a "decode" method. Furthermore, the decode returns an object called "DecoderResult" and it has a method called "getErrorsCorrected". To my opinion, I think this method is what I need to get how many errors there are in the QRcode. However, when I use this method in MATLAB, it always return an empty matrix although I definitely do some change on the original QRcode.
Anyone know what's going on in this method? I had googled this question on the Internet for a while but I couldn't find such problems before. Besides, Is there any way to meet my request? Thanks a lot!
