  "worklet";
  const variation = calculateBlurry(frame);
}, []);

Calculate brightness

import { calculateBrightness } from "@drivekyte/react-native-image-validators";

// ...

const frameProcessor = useFrameProcessor((frame) => {
  "worklet";
  const variation = calculateBrightness(frame);
}, []);

Calculate all variations

import { calculateVariations } from "@drivekyte/react-native-image-validators";
import { useFrameProcessor } from "react-native-vision-camera";
