Class GrayThreshold

java.lang.Object

stream.AbstractProcessor

stream.news.learner.sbdetection.GrayThreshold

All Implemented Interfaces:

stream.Processor, stream.StatefulProcessor

public class GrayThreshold
extends stream.AbstractProcessor

This processor is a classifier, predicting shot boundaries based on the DiffImages of two successive frames. It can only be applied, after the DiffImage has already been calculated. If the average gray value of the DiffImages exceeds a given threshold t, the frame is labeled as a shot boundary.

Method Detail

setT

public void setT(Integer t)

Sets the threshold t to a new value.

Parameters:

t - Threshold

getT

public Integer getT()

Returns the current threshold the processor is working with.

Returns:

Threshold

setGraykey

public void setGraykey(String graykey)

Tells the GrayThreshold processor, where to find the gray value of the pixels.

Parameters:

graykey -

getGraykey

public String getGraykey()

Delivers the string, under which the processor expects the gray value of the input image to be found.

Returns:

the current key, the processor expects the gray value to be stored under.

setPredictionkey

public void setPredictionkey(String predictionkey)

The key under which the classifier shall store the predicted label.

Parameters:

predictionkey -

getPredictionkey

public String getPredictionkey()

Delivers the key, under which the classifier currently stores the predicted label.

Returns:

process

public stream.Data process(stream.Data input)
