## 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.
