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
Matrix<Single> matrix = new Matrix<Single>(width, height);
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 Matrix<double> matrix to XmlDocument:
StringBuilder sb = new StringBuilder();
(new XmlSerializer(typeof(Matrix<double>))).Serialize(new StringWriter(sb), o);
XmlDocument xDoc = new XmlDocument();
xDoc.LoadXml(sb.ToString());
Conversion from XML
You can use the following code to convert a XmlDocument xDoc to Matrix<double>
Matrix<double> matrix = (Matrix<double>)
(new XmlSerializer(typeof(Matrix<double>))).Deserialize(new XmlNodeReader(xDoc));
