TrySetChannelConfidenceThresholds

---

## Declaration

public bool TrySetChannelConfidenceThresholds(Dictionary<SceneSegmentationChannel, float> channelConfidenceThresholds)

#### Summary

Sets the confidence threshold for including the specified semantic channel in the packed semantic
    channel buffer.

#### Remarks

Each semantic channel will use its default threshold value chosen by the model until a new value is set
    by this function during the AR session.
    Changes to the semantic segmentation thresholds are undone by either restarting the subsystem or by calling
    TryResetChannelConfidenceThresholds.

#### Returns

True if the thresholds were set. Otherwise, false.

#### Throws

NotSupportedException -- Thrown when setting confidence thresholds is not     supported by the implementation.

### Parameters

| Name | Type | Summary |
| --- | --- | --- |
| channelConfidenceThresholds | Dictionary<SceneSegmentationChannel, float> | A dictionary consisting of keys specifying the scene segmentation channel that is needed and values between 0 and 1, inclusive, that set the threshold above which the platform will include the specified channel in the packed scene segmentation buffer. The key must be a semantic channel present in the list returned by TryGetChannelNames. |
