Our GstInferenceMeta behaves in a hierarchical manner; i.e, amongst the several predictions a frame might contain, each prediction may contain its own predictions. The inference filter element provides the functionality of selecting which of this predictions to process in further stages of the pipeline, by setting the enable property on each prediction.

Properties

The inference filter exposes the following properties, in order to select which classes to enable/disable, according to the class_id of the classifications of each prediction.

These properties are documented on the following table:

Property	Value	Description
filter-class	-1 - 2147483647. Default: -1	Class id we want to enable. If set to -1, the filter will be disabled.
reset-enable	Boolean. Default: false	Enables all inference meta to be processed.

Example
