Detailed Description

Namespace for all functions is cvv, i.e. cvv::showImage().

Compilation:

• For development, i.e. for cvv GUI to show up, compile your code using cvv with g++ -DCVVISUAL_DEBUGMODE*.
• For release, i.e. cvv calls doing nothing, compile your code without above flag.

See cvv tutorial for a commented example application using cvv.

Function Documentation

debugDMatch() [1/2]

static void cvv::debugDMatch ( cv::InputArray  img1, std::vector< cv::KeyPoint >  keypoints1, cv::InputArray  img2, std::vector< cv::KeyPoint >  keypoints2, std::vector< cv::DMatch >  matches, const impl::CallMetaData &  data, const char *  description = nullptr, const char *  view = nullptr, bool  useTrainDescriptor = true  )

inlinestatic

Add a filled in DMatch <dmatch> to debug GUI.

The matches can are visualized for interactive inspection in different GUI views (one similar to an interactive :draw_matches:drawMatches<>).

Parameters

img1	First image used in DMatch <dmatch>.
keypoints1	Keypoints of first image.
img2	Second image used in DMatch.
keypoints2	Keypoints of second image.
matches
data	See showImage
description	See showImage
view	See showImage
useTrainDescriptor	Use DMatch <dmatch>'s train descriptor index instead of query descriptor index.

debugDMatch() [2/2]

static void cvv::debugDMatch ( cv::InputArray  img1, std::vector< cv::KeyPoint >  keypoints1, cv::InputArray  img2, std::vector< cv::KeyPoint >  keypoints2, std::vector< cv::DMatch >  matches, const impl::CallMetaData &  data, const std::string &  description, const std::string &  view, bool  useTrainDescriptor = true  )

inlinestatic

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

debugFilter() [1/2]

static void cvv::debugFilter ( cv::InputArray  original, cv::InputArray  result, impl::CallMetaData  metaData = impl::CallMetaData(), const char *  description = nullptr, const char *  view = nullptr  )

inlinestatic

Use the debug-framework to compare two images (from which the second is intended to be the result of a filter applied to the first).

debugFilter() [2/2]

static void cvv::debugFilter ( cv::InputArray  original, cv::InputArray  result, impl::CallMetaData  metaData, const ::std::string &  description, const ::std::string &  view = ""  )

inlinestatic

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

debugMode()

static bool cvv::debugMode ( )

inlinestatic

Returns whether debug-mode is active for this TU and thread.

finalShow()

void cvv::finalShow ( )

inline

Passes the control to the debug-window for a last time.

This function must be called once after all cvv calls if any. As an alternative create an instance of FinalShowCaller, which calls finalShow() in its destructor (RAII-style).

setDebugFlag()

static void cvv::setDebugFlag ( bool  active )

inlinestatic

Enable or disable cvv for current translation unit and thread.

(disabled this way has higher - but still low - overhead compared to using the compile flags).

Parameters

active

showImage() [1/2]

static void cvv::showImage ( cv::InputArray  img, impl::CallMetaData  metaData = impl::CallMetaData(), const char *  description = nullptr, const char *  view = nullptr  )

inlinestatic

Add a single image to debug GUI (similar to imshow <>).

Parameters

img	Image to show in debug GUI.
metaData	Properly initialized CallMetaData struct, i.e. information about file, line and function name for GUI. Use CVVISUAL_LOCATION macro.
description	Human readable description to provide context to image.
view	Preselect view that will be used to visualize this image in GUI. Other views can still be selected in GUI later on.

showImage() [2/2]

static void cvv::showImage ( cv::InputArray  img, impl::CallMetaData  metaData, const ::std::string &  description, const ::std::string &  view = ""  )

inlinestatic

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