Real-time feature extraction from video stream data for stream ...

D. Implemented processors in the streams framework

Processor ApplyImageModel

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

matching each shot against an image, representing an anchorshot model. Pixels, that

are black in the model, get ignored, all other pixels get compared pixel-wise. If the

difference between the current image and the model does not exceed a given threshold

t, the shot is predicted to be an anchorshot.

Parameter Type Description Required

model String Tells the processor, where to find the model to be matched. false

t Integer Sets the threshold t to a new value. false

predictionkey String Sets the key under which the classifier shall store the predicted

label.

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

of the image.
