Constructor Detail

CvUndistort

public CvUndistort()

Method Detail

release

public void release()

Description copied from class: CvBase

Frees memory, closes windows, and releases resources.

Overrides:

release in class CvBase

camIndexOptional

protected boolean camIndexOptional()

Description copied from class: CvBase

Whether the camera index is optional on the command line.

Overrides:

camIndexOptional in class CvBase

cmdHelpExt

protected void cmdHelpExt()

Description copied from class: CvBase

Display extra command line help, for subclasses.

Overrides:

cmdHelpExt in class CvBase

guiHelpExt

protected void guiHelpExt()

Description copied from class: CvBase

Display extra GUI help, for subclasses.

Overrides:

guiHelpExt in class CvBase

cmdHelpExtParams

protected java.lang.String cmdHelpExtParams()

Description copied from class: CvBase

Extra command line parameters, for subclasses.

Overrides:

cmdHelpExtParams in class CvBase

process

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

Description copied from class: CvBase

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 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.

Overrides:

process in class CvBase

Returns:

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

handleKeyExt

protected boolean handleKeyExt(int code)

Description copied from class: CvBase

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.

Overrides:

handleKeyExt in class CvBase

initExt

public int initExt(int argc,
                   java.lang.String[] argv,
                   int ate)

Description copied from class: CvBase

Extra initialization, for subclasses.

Overrides:

initExt in class CvBase

ate - the number of command line arguments already eaten by CvBase.init(int, String[])

Returns:

the total number of arguments eaten

main

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