Processors in Package stream.news.anchorshotdetection

This package provides several processors useful for detecting anchorshots in news

videos and creating anchorshot models.

This processor learns an image model, which represents anchorshots, by looking for

areas in anchorshot frames that have constant color values throughout all incoming

anchorshot frames.

Parameter Type Description Required

model String URL of a file, where the model can be stored on the disk. false

image String The name of the attribute that contains the byte array data

of the image.

Table .23.: Parameters of class AnchorshotModelCreator.

true

Processor ApplyDecisionTreeModel

This processor classifies a news video into anchorshots and news report shots, by

applying a decision tree to each example. The decision tree has to be learned using

RapidMiner, as not Decision Tree Learner is implemented in the streams framework

yet.

label.
