Frame Processor Plugins are native functions (written in Objective-C, Swift, C++, Java or Kotlin) that are injected into the VisionCamera JS-Runtime. They can be synchronously called from your JS Frame Processors (using JSI) without ever going over the bridge. Because VisionCamera provides an easy-to-use plugin API, you can easily create a Frame Processor Plugin yourself. Some examples include [Barcode Scanning](https://developers.google.com/ml-kit/vision/barcode-scanning), [Face Detection](https://developers.google.com/ml-kit/vision/face-detection), [Image Labeling](https://developers.google.com/ml-kit/vision/image-labeling), [Text Recognition](https://developers.google.com/ml-kit/vision/text-recognition) and more.
