The GStreamer element is called "rrmotiondetectionbin". This element performs the motion detection, noise reduction and blob detection stages in one simple element/bin. It is very useful if you don't want to separate the different stages described in the Overview section.
Main Properties
- cuda-blob-detection: Use blob detection algorithm (in charge of detecting the motion bounding boxes) implemented in cuda (Blob Detector GPU) otherwise use cpu blob detection. By default it is false.
- grayscale: When enabled, the motion detection is performed over a grayscale image (color dropped). By default it is true.
Access Child Properties
Through the bin you are capable to access and control its internal elements configuration using the following notation:
<element name>::<property name>
The element name corresponds to the name given to the element internally by the bin. For your convenience here is the list of the rrmotiondetectionbin main internal element's names:
- motion_detector of type rrmotiondetection
- motion_denoiser of type rrnoisereduction
- blob_detector that can be of type rrblobdetector or rrcudablobdetector depending of the cuda-blob-detection property.
For instance if you want to change the motion detector algorithm you can set the property motion as follows:
rrmotiondetectionbin motion_detector::motion=mog2
On the hand, if you can to change the kernel size of the motion reduction element you can do it as follows:
rrmotiondetectionbin motion_denoiser::size=5
Please refer to the GStreamer Pipelines section for more examples of child properties in use
