Object class recognition finds objects that belong to pre-defined classes, when they appear in media. For example, if you are processing video captured by a CCTV camera, you could train Media Server to return the locations of pedestrians, cyclists, and cars that appear in the video.
Configuration Parameter | Description |
---|---|
DetectionThreshold | The minimum confidence score necessary for Media Server to output a result. |
Input | The track to analyze. |
MaxInputQueueLength | Can be used to place a limit on latency. |
NumParallel | The maximum number of video frames to analyze simultaneously. |
Recognizer | The recognizer to use for recognizing objects. |
Region | The region of the frame to restrict processing to. |
RegionUnit | The units to use when setting the Region parameter. |
RestrictToInputRegion | Specifies whether to analyze a region of the input image or video frame that is specified in the input record, instead of the entire image. |
SampleInterval | The interval at which frames are selected to be analyzed. |
SyncDatabase | Specifies whether to synchronize with the training database before starting analysis. |
Type | The analysis engine to use. Set this parameter to ObjectClassRecognition . |
Output track | Description | Output1This column indicates whether the information contained in the track is included by default in the output created by an output task (when you don't set the Input parameter for the output task). |
