# latestSuppressionMask Source: https://www.nianticspatial.com/docs/api/swift/NSDK.NSDKSceneSegmentationSession.method-latestSuppressionMask/ latestSuppressionMask --- ## Declaration func latestSuppressionMask() -> NSDKAsyncState #### Summary Retrieves the latest suppression mask for semantic processing. This method returns a binary mask indicating areas that should be ignored or suppressed during semantic processing. Suppression masks are useful for filtering out regions that are not relevant for semantic understanding, such as areas with poor image quality. #### Returns An NSDKAsyncState containing either the latest SceneSegmentationResult, or an AwarenessError. #### Suppression Mask Usage Suppression masks are binary images where: - **0**: Areas to be suppressed (ignored in semantic processing) - **1**: Areas to be processed normally Use suppression masks to improve semantic processing quality by excluding problematic regions from analysis. ---
