Depth as Generic Parameter
A Matrix is defined by its generic parameters depth. To create a 32bit floating point matrix, in Emgu CV it is done by calling <source lang="csharp"> Matrix<Single> matrix = new Matrix<Single>(width, height); </source>
Matrix Depth
The types of depth supported in Emgu CV 1.4.0.0 include
- Byte
- SByte
- Single (float)
- Double
- UInt16
- Int16
- Int32 (int)
XML Serialization
Conversion to XML
You can use the following code to convert an <code>Matrix<double> matrix</code> to <code>XmlDocument</code>: <source lang="csharp"> StringBuilder sb = new StringBuilder(); (new XmlSerializer(typeof(Matrix<double>))).Serialize(new StringWriter(sb), o); XmlDocument xDoc = new XmlDocument(); xDoc.LoadXml(sb.ToString()); </source>
Conversion from XML
You can use the following code to convert a <code>XmlDocument xDoc</code> to <code>Matrix<double></code> <source lang="csharp"> Matrix<double> matrix = (Matrix<double>) (new XmlSerializer(typeof(Matrix<double>))).Deserialize(new XmlNodeReader(xDoc)); </source>
