Method Detail

handleKeyExt

protected boolean handleKeyExt(int code)

Keypresses not handled by the default implementation of handleKey() are passed here.

Default impl just prints the keycode.

Overriding this is one way that subclasses can handle extra keypresses.

This impl handles keycodes for Kinect demo functions.

Overrides:

handleKeyExt in class CvBase

guiHelpExt

protected void guiHelpExt()

Display extra GUI help, for subclasses.

This impl handles keycodes for Kinect demo functions.

Overrides:

guiHelpExt in class CvBase

handleMouse

protected void handleMouse(int event,
               int x,
               int y,
               int flags)

Handle mouse events.

This impl triggers RGB/XYZ dump on click.

Overrides:

handleMouse in class CvBase

Parameters:

event - one of the CV_EVENT_* constants (see opencv_highgui.java in the JavaCV sources for a list)

x - the x pixel coordinate of the mouse event

y - the y pixel coordinate of the mouse event

flags - bitmask of the CV_EVENT_FLAG_* constants (see opencv_highgui.java in the JavaCV sources for a list)

Default impl prints a message using CvBase.mouseEventToString(int, int, int, int) except for CV_EVENT_MOUSEMOVE.

Overriding this is one way that subclasses can handle mouse events.

process

protected com.googlecode.javacv.cpp.opencv_core.IplImage process(com.googlecode.javacv.cpp.opencv_core.IplImage frame)

Process the given frame.

Default impl is identity.

Note that the passed image may not be mutated. So to do any significant processing, you will need to allocate your own return image. It is typically best to do this once for the first frame, store the results in subclass instance variables, and then deallocate any allocated space in the subclass destructor.

All frames are guaranteed to have the same dimensions and pixel format.

This will be called for every iteration of CvBase.mainLoop(), even while paused. You may use the various instance fields (CvBase.frameN, CvBase.capImage, CvBase.paused, CvBase.dbg, etc) to determine what operations to perform. Of course, when writing a subclass, you may also add your own fields.

This impl handles Kinect demo functions.

Overrides:

process in class CvBase

Returns:

the processed image, null will cause image display to be skipped for this frame

release

public void release()

Frees memory, closes windows, and releases resources.

This impl also releases depthBGR.

Overrides:

release in class CvBase

main

public static void main(java.lang.String[] argv)

Program entry point.
