Class VideoAnalyser<T extends Image<?,T>>

java.lang.Object

org.openimaj.video.Video<T>

org.openimaj.video.processor.VideoProcessor<T>

org.openimaj.video.analyser.VideoAnalyser<T>

Type Parameters:

T - The type of the video frame to be analysed

All Implemented Interfaces:

Closeable, AutoCloseable, Iterable<T>

Direct Known Subclasses:

FMeanVarianceField, MBFMeanVarianceField, MotionEstimator

public abstract class VideoAnalyser<T extends Image<?,T>>
extends VideoProcessor<T>

This class is analagous to the ImageAnalyser class for analysing image. It should be used to make analysis and measurements on video frames without altering the frames themselves.

This class overrides VideoProcessor to inherit many of its abilities (chainability etc.) but the processFrame method will always return the input frame having called analyseFrame. The analyseFrame method should not alter the input frame.
