Member Function Documentation
| virtual CV_WRAP void clear | ( | ) | [virtual, inherited] |
| virtual CV_WRAP void compute | ( | InputArray | image, |
| OutputArray | features | ||
| ) | const [pure virtual] |
Computes features sby input image.
- Parameters:
-
image Input image (CV_32FC1). features Feature vector (CV_32FC1).
| virtual bool empty | ( | ) | const [virtual, inherited] |
| String getDefaultName | ( | ) | const [virtual, inherited] |
Returns the algorithm string identifier.
This string is used as top level xml/yml node tag when the object is saved to a file or string.
Definition at line 65 of file algorithm.cpp.
| virtual CV_WRAP int getNumBands | ( | ) | const [pure virtual] |
- Returns:
- The number of filter bands used for computing BIF.
| virtual CV_WRAP int getNumRotations | ( | ) | const [pure virtual] |
- Returns:
- The number of image rotations.
| static Ptr<_Tp> load | ( | const String & | filename, |
| const String & | objname = String() |
||
| ) | [static, inherited] |
Loads algorithm from the file.
- Parameters:
-
filename Name of the file to read. objname The optional name of the node to read (if empty, the first top-level node will be used)
This is static template method of Algorithm. It's usage is following (in the case of SVM):
Ptr<SVM> svm = Algorithm::load<SVM>("my_svm_model.xml");
In order to make this method work, the derived class must overwrite Algorithm::read(const FileNode& fn).
| static Ptr<_Tp> loadFromString | ( | const String & | strModel, |
| const String & | objname = String() |
||
| ) | [static, inherited] |
Loads algorithm from a String.
- Parameters:
-
strModel The string variable containing the model you want to load. objname The optional name of the node to read (if empty, the first top-level node will be used)
This is static template method of Algorithm. It's usage is following (in the case of SVM):
Ptr<SVM> svm = Algorithm::loadFromString<SVM>(myStringModel);
| virtual void read | ( | const FileNode & | fn ) | [virtual, inherited] |
Reads algorithm from the file node.
This is static template method of Algorithm. It's usage is following (in the case of SVM):
Ptr<SVM> svm = Algorithm::read<SVM>(fn);
In order to make this method work, the derived class must overwrite Algorithm::read(const FileNode& fn) and also have static create() method without parameters (or with all the optional parameters)
| void save | ( | const String & | filename ) | const [virtual, inherited] |
Saves the algorithm to a file.
In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).
Reimplemented in FaceRecognizer.
Definition at line 56 of file algorithm.cpp.
