Constructor Detail

GreyscaleSlitScanProcessor

public GreyscaleSlitScanProcessor(FImage timemap)

Default constructor for using the video processor in an ad-hoc manner. Uses a default cache size of 240 steps.

Parameters:

timemap - The time map image

GreyscaleSlitScanProcessor

public GreyscaleSlitScanProcessor(FImage timemap,
                                  int cacheSize)

Default constructor for using the video processor in an ad-hoc manner.

Parameters:

timemap - The time map image

cacheSize - The number of frames to retain for creating the slitscan effect

GreyscaleSlitScanProcessor

public GreyscaleSlitScanProcessor(Video<MBFImage> video,
                                  FImage timemap,
                                  int cacheSize)

Constructor for creating a video processor which is chainable.

Parameters:

video - The video to process

timemap - the time map

cacheSize - The number of frames to retain for creating the slitscan effect

GreyscaleSlitScanProcessor

public GreyscaleSlitScanProcessor(int cacheSize)

Default constructor for using the video processor in an ad-hoc manner.

Parameters:

cacheSize - The number of frames to retain for creating the slitscan effect

GreyscaleSlitScanProcessor

public GreyscaleSlitScanProcessor(Video<MBFImage> video,
                                  int cacheSize)

Constructor for creating a video processor which is chainable.

Parameters:

video - The video to process

cacheSize - The number of frames to retain for creating the slitscan effect

Method Detail

processFrame

public MBFImage processFrame(MBFImage frame)

Description copied from class: VideoProcessor

Process a frame in this video. The processor must determine itself what is to be done with the frame that is processed. It is suggest that subclass processors add listeners for processed frames if they are required. The implementation must process the frame in-place and the frame should be returned.

Specified by:

processFrame in class VideoProcessor<MBFImage>

Parameters:

frame - The frame to process.

Returns:

the processed frame
