How to Benchmark Barcode SDK Performance in Python

On StackOverflow, you may have seen this kind of question: why some open-source barcode SDK failed to decode some barcode? Usually, there are three optional workarounds: improve the input image quality, improve the barcode algorithm, or find a better barcode SDK.  ZXing and ZBar are probably the most-welcomed open-source barcode SDKs, but their algorithms rarely enhanced over the past years. Why not use commercial barcode SDK if free SDK is not ideal? Last week, I published an article demonstrating how to use ZXing and ZBar in Python. In this article, I will show you how to use Dynamsoft Barcode Reader in Python, as well as compare its performance to ZXing and ZBar.

How to Use Python ZXing and Python ZBar on Windows 10

When creating a barcode reader app with a free barcode SDK, you may come up with ZXing instantly. ZXing is an open-source barcode reading and decoding library implemented in Java. There are some third-party projects, either ports or bindings, available for other programming languages. So if you want to create a Python barcode reader, you can use Python ZXing, which is a Python wrapper for invoking ZXing Java class. If you care about the performance, we can use Python ZBar, a Python wrapper for the ZBar C++ code, as a comparison.

How to Build ImageMagick for Software Distribution on Windows

If you have read the article How to Benchmark Barcode SDK Performance – ZXing vs ZBar, you may have noticed that ZBar relies on ImageMagick. ImageMagick is an open source software suite that capable of reading a variety of images. If you just want to write a barcode testing program, Windows Binary Release of ImageMagick is enough. However, if you consider distributing your applications, the Windows binary distribution is not suitable. Why? I’ll show you in the following content.

How to Benchmark Barcode SDK Performance – ZXing vs ZBar

I saw many posts arguing the performance winner between open-source barcode SDKs – ZXing and ZBar. As an engineer, who is developing commercial barcode reader software for Dynamsoft, I am curious about which open source project is better, ZXing or ZBar? Considering ZXing is implemented in Java, whereas ZBar is implemented in C/C++. To fairly compare their performance, I decided to use JNI to wrap ZBar C/C++ source code and benchmark them in a Java program.
