The library provides a Qt widget for viewing OpenCV matrices. It can show various formats like CV_8UC, CV_16US, CV_32F,...

Some other features:

• Zoom
• Simple markers
• Saving the graphical representation (but without markers)
• Table for viewing the pixel values
• Qt Designer plugin available

Requirements: OpenCV2, Qt5 (there's a Qt4 branch available)

• Switch to the project directory of cvwidgets
• cmake . && make
• su root
• (type in your superuser password)
• make install

A project example is given in the subfolder example

If you use qmake (the default build system of QtCreator), then add this line to your .pro file:

LIBS += -lcvwidgets

(like in the example/cvwidgets_example.pro file)

Add to your CMakeLists.txt

target_link_libraries(your_project_name cvwidgets)

(like in the example/CMakeLists.txt)
