latestConfidence

Declaration

func latestConfidence(channel: SceneSegmentationChannels) throws(NSDKError) -> NSDKAsyncState<SceneSegmentationResult, AwarenessError>

Summary

Retrieves the latest confidence map for a specific semantic channel.
This method returns a confidence map where each pixel value represents the confidence
score (0.0–1.0) that the pixel belongs to the specified semantic category. Higher
confidence values indicate stronger belief in the semantic classification.

Returns

An NSDKAsyncState containing either the latest SceneSegmentationResult,
or an AwarenessError.

Throws

NSDKError.invalidArgument if zero or more than one channel is specified.

Confidence Interpretation

Confidence values range from 0.0 to 1.0:

0.0: Definitely not the specified semantic category
0.5: Uncertain classification
1.0: Definitely the specified semantic category Use confidence thresholds to filter results based on your application's needs.

Parameters

Name	Type	Summary
channel	SceneSegmentationChannels	The semantic channel; throws if multiple channels are given.
