# VTLowLatencySuperResolutionScalerConfiguration

An object you use to configure frame processor for low-latency super-resolution scaler processing.

## Declaration

```swift
class VTLowLatencySuperResolutionScalerConfiguration
```

## Overview

Overview Use this object to configure a VTFrameProcessor. Query this interface also for important operating details, like the pixel buffer attributes required for frames you submit to the processor. important: When calling startSession(configuration:) to create a VTLowLatencySuperResolutionScaler session, ML model loading may take longer than a frame time. Avoid blocking the UI thread or stalling frame rendering pipelines during this call.
