Detailed Description
This algorithm converts images to median threshold bitmaps (1 for pixels brighter than median luminance and 0 otherwise) and than aligns the resulting bitmaps using bit operations.
It is invariant to exposure, so exposure values and camera response are not necessary.
In this implementation new image regions are filled with zeros.
For more information see GW03 .

| virtual CV_WRAP Point calculateShift | ( | InputArray | img0, |
| InputArray | img1 | ||
| ) | [pure virtual] |
Calculates shift between two images, i.
e. how to shift the second image to correspond it with the first.
- Parameters:
-
img0 first image img1 second image
| virtual CV_WRAP void clear | ( | ) | [virtual, inherited] |
Clears the algorithm state.
Reimplemented in DescriptorMatcher, and FlannBasedMatcher.
| virtual CV_WRAP void computeBitmaps | ( | InputArray | img, |
| OutputArray | tb, | ||
| OutputArray | eb | ||
| ) | [pure virtual] |
Computes median threshold and exclude bitmaps of given image.
- Parameters:
-
img input image tb median threshold bitmap eb exclude bitmap
| virtual bool empty | ( | ) | const [virtual, inherited] |
| virtual CV_WRAP 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.
| 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 CV_WRAP void process | ( | InputArrayOfArrays | src, |
| std::vector< Mat > & | dst | ||
| ) | [pure virtual] |
Short version of process, that doesn't take extra arguments.
- Parameters:
-
src vector of input images dst vector of aligned images
| virtual CV_WRAP void process | ( | InputArrayOfArrays | src, |
| std::vector< Mat > & | dst, | ||
| InputArray | times, | ||
| InputArray | response | ||
| ) | [pure virtual] |
Aligns images.
- Parameters:
-
src vector of input images dst vector of aligned images times vector of exposure time values for each image response 256x1 matrix with inverse camera response function for each pixel value, it should have the same number of channels as images.
Implements AlignExposures.
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)
Reimplemented in DescriptorMatcher, and FlannBasedMatcher.
| virtual void read | ( | const FileNode & | fn ) | [virtual, inherited] |
Reads algorithm parameters from a file storage.
Reimplemented in DescriptorMatcher, and FlannBasedMatcher.
| virtual CV_WRAP 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).
| virtual CV_WRAP void shiftMat | ( | InputArray | src, |
| OutputArray | dst, | ||
| const Point | shift | ||
| ) | [pure virtual] |
Helper function, that shift Mat filling new regions with zeros.
- Parameters:
-
src input image dst result image shift shift value
| virtual void write | ( | FileStorage & | fs ) | const [virtual, inherited] |
Stores algorithm parameters in a file storage.
Reimplemented in DescriptorMatcher, and FlannBasedMatcher.
