Isolates

Requirements​

Isolates​

Isolates help eliminate freezes when launching heavy models. Some classes have received an asynchronous version.

  • Capturer - AsyncCapturer(createAsyncCapturer)
  • Recognizer - AsyncRecognizer(createAsyncRecognizer)
  • ProcessingBlock - AsyncProcessingBlock(createAsyncProcessingBlock)

The principle of working with asynchronous versions remains the same. All methods for working with classes, as well as methods for creation, have become asynchronous.

Create isolates​

Future<AsyncCapturer> createCapturer(FacerecService service) async {
  return await service.createAsyncCapturer(Config("common_capturer_uld_fda.xml"));
}

Future<AsyncRecognizer> createRecognizer(FacerecService service) async {
  return await service.createAsyncRecognizer("method12v30_recognizer.xml");
}
  
Future<AsyncProcessingBlock> createProcessingBlock(FacerecService service) async {
  return await service.createAsyncProcessingBlock({
    "unit_type": "LIVENESS_ESTIMATOR", 
    "modification": "2d_light", 
    "version": 1
  });
}

Isolate usage demonstration​

Demo Flutter sample with the Face SDK plugin is available in the examples/flutter/isolates_demo directory of Face SDK distribution kit.
