Collaboration diagram for QtCvWrapper:
Public Slots | |
| void | slotImageOpened () |
| slot is called when a new image is opened to synchronize the IplImage | |
| void | slotSnakeButtonPressed () |
| when the snake buttin is hit the algorithm should start | |
| void | slotTest () |
| just does a small demo with a simple ellipse in the image | |
| void | slotInitCurve () |
| does initialisation of the initial snake | |
| void | slotIterationOn () |
| iteration visualisation is turned on | |
| void | slotIterationOff () |
| iteration visualisation is turned off | |
| void | slotIterationStep () |
| iteration visualisation is turned on with user interaction | |
Public Member Functions | |
| QtCvWrapper (MainProgram *parent, MainWindow *gui) | |
| constructs the wrapper between Qt and OpenCV | |
| ~QtCvWrapper (void) | |
| destructor | |
| bool | iterate () |
| indicates if the iteration is schown or not | |
| bool | step () |
| indicates if the iteration is schown or not | |
Private Member Functions | |
| void | createTestImage (CvPoint center, CvSize axes, CvScalar color, CvScalar background) |
| a simple test image with an ellipse is created | |
| void | convertImage (IplImage *src, QImage *dst) |
| converts an ipl image to a qimage (hopefully) | |
| CvPoint * | createEllipse (QPoint ulPt, QPoint lrPt, int numSegments) |
| creates an ellipse with the initialized upper left and lower right boundingbox vertices | |
Private Attributes | |
| MainProgram * | m_parent |
| MainWindow * | m_gui |
| parent that created the wrapper | |
| Snake * | m_snake |
| pointer to the actual gui | |
| IplImage * | m_iplImg |
| m_snake is used for applying the snake algorithm to m_iplImg | |
| bool | m_iterate |
| the actual shown and processed image | |
| bool | m_step |
| switches iterations on/off | |
The QtCvWrapper implements some connections between the Qt GUI and the Intel OpenCV library. Also signal and slot connections from Qt to the non-Qt part are handeled here. Most of the functions from the Snake class are initiated from this wrapper when certain signals comming from the GUI.
| parent | represents the connection to the Image-Processing part | |
| gui | holds the pointer to the GUI |
