By using this module, you can view values of a Mat type variable(OpenCV) in real-time, similar to the famous visual studio plugin tool "ImageWatch". This module does not need to enter into any breakpoint at debug mode, and images can be viewed directly in real-time when the program is running.

Currently, this module only supports c++. In the future, this module possibly will support pyhton.

Currently supports:

• mouse drag => translate image
• mouse wheel => scale image
• use mouse to enlarge image => display values in grid mode
• mouse hover => display value (Tiptool)
• use left mouse to double click => set roi of image to center
• use right mouse to click => turn on / turn off global window

The main interface of the program is defined in the following two files

• src/eunit/emat/emat_viewer.hpp # Window visualization support (Imshow, ...)
• src/eunit/emat/emat_visual.hpp # Image visualization support (applyColorMap, vhoncat, ...)

• GCC 5.4
• cmake 2.6 +
• opencv 3.* / 4.*

1. this project relies on OpenCV, make sure you have OpenCV compiled.
2. compile

• cmake .
• make

1. void img_show_cache(const string& win_name, const Size& win_size, const Mat& img_colored, const Mat& img_raw, const vector<s_viewer_text>& texts)

• cache an image: window will be updated/shown after call "imshow"
• @param win_name [in] name of window.
• @param win_size [in] size of window.
• @param img_colored [in] image to display (must be CV_8UC3).
• @param img_raw [in] image with related values corresponding to img_colored (Should be same size with img_colored, but can be different types)
• @param texts [in] texts will be rendered on screen (subtitle)
• @return

2. void visible_wins(vector<string>& win_names)

• get visible windows
• @param win_names [out] wisible windows
• @return

3. bool is_win_closed(const string& win_names)

• is window closed
• @param win_names [in] name of window
• @return

4. void imgs_show(bool reopen_win)

• imshow all images cached
• @param reopen_win [in] whether reopen window, when a window is closed by user.
• @return

5. void destroy_all()

• destroy all winodws
• @return

6. void destroy(const string& win_name)

• destroy specific window
• @param win_names [in] name of window

addition:

1. If you want to view windows in your own UI, just override these functions (Easy to combine with Qt, ...)

• destroy_window
• named_window
• resize_window
• img_show
• get_window_image_rect
• set_mouse_callback
• get_mouse_wheel_delta

1. void vis_gconcat(const vector<Mat>& imgs, const uint32_t& cols, Mat& res)

• apply grid concat
• @param imgs [in] array with Mat type (must be same cv_type, but can be different size)
• @param cols [in] the max count of images can be put in each colume
• @param res [out] variable with Mat type (CV_8UC3)
• @return

2. void vis_vconcat(const vector<Mat>& imgs, Mat& res)

• apply vertical concat
• @param imgs [in] array with Mat type (must be same cv_type, but can be different size)
• @param res [out] variable with Mat type (CV_8UC3)
• @return

3. void vis_hconcat(const vector<Mat>& imgs, Mat& res)

• apply horizontal concat
• @param imgs [in] array with Mat type (must be same cv_type, but can be different size)
• @param res [out] variable with Mat type (CV_8UC3)
• @return

4. void vis_colormap_jet(const Mat& img, Mat& res)

• apply COLORMAP_JET
• @param img [in] variable with Mat type (must be same cv_type, but can be different size)
• @param res [out] variable with Mat type (CV_8UC3)
• @return

5. void vis_gray(const Mat& img, Mat& res)

• apply normalization
• @param img [in] variable with Mat type (must be same cv_type, but can be different size)
• @param res [out] variable with Mat type (CV_8UC3)
• @return
