#### Overview of this book

There are many algorithms for data analysis and it’s not always possible to quickly choose the best one for each case. Implementation of the algorithms takes a lot of time. With the help of Mathematica, you can quickly get a result from the use of a particular method, because this system contains almost all the known algorithms for data analysis. If you are not a programmer but you need to analyze data, this book will show you the capabilities of Mathematica when just few strings of intelligible code help to solve huge tasks from statistical issues to pattern recognition. If you're a programmer, with the help of this book, you will learn how to use the library of algorithms implemented in Mathematica in your programs, as well as how to write algorithm testing procedure. With each chapter, you'll be more immersed in the special world of Mathematica. Along with intuitive queries for data processing, we will highlight the nuances and features of this system, allowing you to build effective analysis systems. With the help of this book, you will learn how to optimize the computations by combining your libraries with the Mathematica kernel.

## Recognizing barcodes

The information in the form of a barcode is compact and can be easily recognized by software. In Mathematica, there is a `BarcodeRecognize` function, which can recognize barcodes from an image and provide their meaning. It recognizes 11 one-dimensional barcodes, including the following:

 "UPC" UPC-A 12 numerical digits "UPCE" UPC-E 6 numerical digits "EAN8" EAN-8 8 numerical digits "EAN13" EAN-13 13 numerical digits "Code39" Code 39 Up to 43 characters of uppercase letters, numeric digits, and special characters such as -, ., \$, /,+, %, and space "Code93" Code 93 Uppercase letters, numeric digits, and special characters such as -, ., \$, /, +, %, and space "Code128" Code 128 Up to 80 ASCII characters "ITF" ITF Up to 80 numerical digits of an even length "Codabar" Codabar Numerical digits and special characters such as :, /, +, . "GS1" GS1 DataBar (or RSS) 14 numerical digits "ExpandedGS1" GS1 Expanded and Expanded Stacked 74 digits or 41 alphanumeric...
