Client-Side Quality Gates

The secret to highly accurate embeddings isn't just the model—it's the data quality fed into the model. Relying entirely on server-side validation wastes bandwidth and frustrates users. Our integration libraries prioritize aggressive client-side validation.

Implementing Expo Camera

When building a React Native application for your insurance portal, you must capture multiple frames to ensure stability. Here is the architectural approach:

// Pseudo-code implementation pattern
const handleFrameUpdate = (frame) => {
  // 1. Calculate Laplacian variance for blur detection
  if (computeBlur(frame) > 50) return setStatus("Too blurry");
  
  // 2. Check ambient brightness
  if (computeBrightness(frame) < 50) return setStatus("Needs more light");
  
  // 3. Buffer valid frames
  frameBuffer.push(frame);
  if (frameBuffer.length >= 3) {
    submitBestFrame(frameBuffer);
  }
}

By dropping low-quality frames before they ever hit the network, the user experience feels instantaneous and your API costs remain minimal.
