Detailed Description

Inverse camera response function is extracted for each brightness value by minimizing an objective function as linear system.

Objective function is constructed using pixel values on the same position in all images, extra term is added to make the result smoother.

For more information see [24] .

Member Function Documentation

clear()

virtual void cv::Algorithm::clear ( )

inlinevirtualinherited

Clears the algorithm state.

Reimplemented in cv::FlannBasedMatcher, and cv::DescriptorMatcher.

empty()

virtual bool cv::Algorithm::empty ( ) const

inlinevirtualinherited

Returns true if the Algorithm is empty (e.g.

in the very beginning or after unsuccessful read

Reimplemented in cv::DescriptorMatcher, cv::ml::StatModel, cv::Feature2D, and cv::BaseCascadeClassifier.

getDefaultName()

virtual String cv::Algorithm::getDefaultName ( ) const

virtualinherited

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.

Reimplemented in cv::AKAZE, cv::KAZE, cv::SimpleBlobDetector, cv::GFTTDetector, cv::AgastFeatureDetector, cv::FastFeatureDetector, cv::MSER, cv::ORB, cv::BRISK, and cv::Feature2D.

getLambda()

virtual float cv::CalibrateDebevec::getLambda ( ) const

pure virtual

getRandom()

virtual bool cv::CalibrateDebevec::getRandom ( ) const

pure virtual

getSamples()

virtual int cv::CalibrateDebevec::getSamples ( ) const

pure virtual

load()

template<typename _Tp >

static Ptr<_Tp> cv::Algorithm::load ( const String &  filename, const String &  objname = String()  )

inlinestaticinherited

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).

References CV_Assert, cv::FileNode::empty(), cv::FileStorage::getFirstTopLevelNode(), cv::FileStorage::isOpened(), and cv::FileStorage::READ.

Here is the call graph for this function:

loadFromString()

template<typename _Tp >

static Ptr<_Tp> cv::Algorithm::loadFromString ( const String &  strModel, const String &  objname = String()  )

inlinestaticinherited

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);

References CV_WRAP, cv::FileNode::empty(), cv::FileStorage::getFirstTopLevelNode(), cv::FileStorage::MEMORY, and cv::FileStorage::READ.

Here is the call graph for this function:

process()

virtual void cv::CalibrateCRF::process ( InputArrayOfArrays  src, OutputArray  dst, InputArray  times  )

pure virtualinherited

Recovers inverse camera response.

Parameters

src	vector of input images
dst	256x1 matrix with inverse camera response function
times	vector of exposure time values for each image

read() [1/2]

virtual void cv::Algorithm::read ( const FileNode &  fn )

inlinevirtualinherited

Reads algorithm parameters from a file storage.

Reimplemented in cv::FlannBasedMatcher, cv::DescriptorMatcher, and cv::Feature2D.

read() [2/2]

template<typename _Tp >

static Ptr<_Tp> cv::Algorithm::read ( const FileNode &  fn )

inlinestaticinherited

Reads algorithm from the file node.

This is static template method of Algorithm. It's usage is following (in the case of SVM):

cv::FileStorage fsRead("example.xml", FileStorage::READ);
Ptr<SVM> svm = Algorithm::read<SVM>(fsRead.root());

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)

save()

virtual void cv::Algorithm::save ( const String &  filename ) const

virtualinherited

Saves the algorithm to a file.

In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

setLambda()

virtual void cv::CalibrateDebevec::setLambda ( float  lambda )

pure virtual

setRandom()

virtual void cv::CalibrateDebevec::setRandom ( bool  random )

pure virtual

setSamples()

virtual void cv::CalibrateDebevec::setSamples ( int  samples )

pure virtual

write() [1/2]

virtual void cv::Algorithm::write ( FileStorage &  fs ) const

inlinevirtualinherited

Stores algorithm parameters in a file storage.

Reimplemented in cv::FlannBasedMatcher, cv::DescriptorMatcher, and cv::Feature2D.

References CV_WRAP.

Referenced by cv::Feature2D::write(), and cv::DescriptorMatcher::write().

Here is the caller graph for this function:

void cv::Algorithm::write ( const Ptr< FileStorage > &  fs, const String &  name = String()  ) const

inherited

simplified API for language bindings This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
