createCompiledFromBuffer static method

Future<IrisLandmark> createCompiledFromBuffer(Uint8List modelBytes)

Creates an iris landmark model backed by LiteRT CompiledModel.

Implementation

static Future<IrisLandmark> createCompiledFromBuffer(
  Uint8List modelBytes,
) async {
  // The 64x64 iris model is below the compute size where Metal dispatch
  // pays off: measured in-app (macOS arm64, median), CompiledModel CPU runs
  // it in ~0.50 ms vs ~0.68 ms for GPU|CPU async. Pin it to the CPU.

    modelBytes,

  );
