How to convert xml to voc format

To convert XML to VOC format, you can use a conversion tool, such as the VOCDevkit MATLAB toolbox or labelImgx2voc. The conversion involves the following steps: 1. Load the XML file; 2. Generate the VOC comment file; 3. Export the VOC file. Tip: Make sure that the XML and image files are in the same directory and verify the accuracy of the VOC files after conversion.

XML to VOC format

XML (Extensible Markup Language) and VOC (Visual Object Category) are two formats for storing image annotations. In some cases, it is necessary to convert XML annotations to VOC format. Here's how to convert:

Step 1: Use the Conversion Tool

You can use tools specifically for converting XML to VOC format. Some popular tools include:

• VOCDevkit MATLAB Toolbox
• labelImg
• x2voc

Step 2: Load the XML file

In the conversion tool of your choice, load the XML file to be converted. The tool parses the XML file and extracts image annotation information.

Step 3: Generate VOC annotation file

The conversion tool will use information from the XML file to generate an annotated file (usually .xml) in VOC format. This file contains the following information:

• Image file path
• Bounding box, category and confidence of an object
• Metadata (such as image size)

Step 4: Export the VOC file

After generating the VOC comment file, export it to the desired directory. These files can now be used for other tasks such as object detection training or verification.

hint:

• Make sure that the XML file and image file are stored in the same directory.
• If some information is missing in the XML file, such as confidence, the conversion tool may use the default value.
• Verify the converted VOC comment file to ensure its accuracy.
