GARFrame(Semantics)

The latest semantic confidence image for the GARFrame as a CVPixelBuffer .

Each pixel is an 8-bit integer representing the confidence of the semantic label, with 0 representing the lowest confidence and 255 representing the highest confidence.

GARFrame retains the semantic CVPixelBuffer. Holding references to GARFrames will eventually exhaust resources.

GARFrame.semanticConfidenceImage will be nil if GARSessionConfiguration does not have GARSemanticModeEnabled set. Use isSemanticModeSupported: (GARSession(Semantics)) to check for support for the Scene Semantics API.

GARFrame.semanticConfidenceImage may be nil for the first few frames after initializing semantics, or if memory is exhausted due to retaining old GARFrames.

The latest semantic image for the GARFrame as a CVPixelBuffer .

Each pixel in the image is an 8-bit integer representing a semantic class label: see GARSemanticLabel for a list of pixel labels and the Scene Semantics Developer Guide for more information.

Retrieves the fraction of the most recent semantics frame that are queryLabel.

Queries the semantic image provided by GARFrame.semanticImage for pixels labeled by queryLabel. This call is more efficient than retrieving the CVPixelBuffer and performing a pixel-wise search for the detected labels.

If GARFrame.semanticImage is nil, fractionForSemanticLabel: will return 0.0.
