## Discussion

Discussion This property returns the array of semantic segmentation types that’s available given the current session configuration. This property is key-value observable. important: The value of this property may change when switching cameras or formats. When this property changes, enabledSemanticSegmentationMatteTypes reverts to an empty array. If you’ve previously opted in for delivery of one or more semantic segmentation mattes, you need to set up your enabledSemanticSegmentationMatteTypes again.
