This is a little experiment related to my latest effort of bringing zxing-cpp to the .NET community.
Looking at nuget.org for barcode reader libraries there are a bunch of options of which I took two of the most popular:
- Dynamsoft (a .NET wrapper around the commercial Dynamsoft c++ library)
- ZXing.Net (an open source C# port of the ZXing java library)
- ZXingCpp (a .NET wrapper around the open source zxing-cpp c++ library)
To run a simple benchmark comparison execute
dotnet run -- <image-file-or-directory, ...>When run for this image results are as follows on my 4 year old mobile Core i9 CPU:
ZXing.Net found 9 barcodes in 1 images in 3215ms
Dynamsoft found 14 barcodes in 1 images in 207ms
ZXingCpp found 14 barcodes in 1 images in 68ms
Executing with the 'false positive' test image results in:
ZXing.Net found 1 barcodes in 1 images in 1103ms
Dynamsoft found 0 barcodes in 1 images in 226ms
ZXingCpp found 0 barcodes in 1 images in 21ms
Letting it run through all the test images we get:
ZXing.Net found 890 barcodes in 1079 images in 51917ms
Dynamsoft found 960 barcodes in 1079 images in 28422ms
ZXingCpp found 957 barcodes in 1079 images in 5077ms
Doing the same with the --single mode, which looks for at most one barcode per image, results in:
ZXing.Net found 858 barcodes in 1079 images in 24502ms
Dynamsoft found 940 barcodes in 1079 images in 25739ms
ZXingCpp found 932 barcodes in 1079 images in 2625ms
For this set of very challenging QRCodes we get:
ZXing.Net found 323 barcodes in 537 images in 291s
Dynamsoft found 895 barcodes in 537 images in 105s
ZXingCpp found 969 barcodes in 537 images in 52s
My personal and "biased" conclusion: use ZXingCpp ;-)
