Read QR code with BoofCV JAR in command line Windows

Question

I used Zxing library for reading QR codes, however, the failure ratio to read QR codes is quite high and was looking for alternatives.

BoofCV looks good according to tests: https://boofcv.org/index.php?title=Performance:QrCode

However, I'm struggling to make it work and find any tutorials in Windows command line using JAR files.

I have the latest 0.33.1 release libraries (https://sourceforge.net/projects/boofcv/files/v0.33.1/):

Is there any simple way to run from command line, I was expecting something like:

java -jar boofcv-recognition-0.33.1.jar -inputQRCodeImagePath [path to local image with QR code]

And then in command line to get text output of what was encoded in QR code, which I can process further.

Thanks in advance!

This feature has was added a few months ago. Download the BoofApplications, then follow the steps below:

1. unzip BoofApplications.zip
2. cd BoofApplications
3. java -jar applications.jar BatchScanQrCodes

That will print out help. To scan for QR codes in all directories in a path do the following:

java -jar applications.jar BatchScanQrCodes --Recursive -i path/to/input -o path/to/output

Every 50 files it will print out the number of files scanned. Took less than a minute to scan the entire test set of QR codes 562 images. You will then have a file which looks like:

# Found QR Codes inside of images
# ../ValidationBoof/data/fiducials/qrcodes
# Format:
# <File Name> <Total Found>
# message encoded with URLEncoder
