A InstanceSegmentationModelSources config specifying which model to load.

Example

const { isReady, isGenerating, forward, error, downloadProgress, getAvailableInputSizes, runOnFrame } =
  useInstanceSegmentation({
    model: {
      modelName: 'yolo26n-seg',
      modelSource: 'https://huggingface.co/.../yolo26n-seg.pte',
    },
  });

if (!isReady) {
  return <Text>Loading: {(downloadProgress * 100).toFixed(0)}%</Text>;
}

const results = await forward('path/to/image.jpg', {
  confidenceThreshold: 0.5,
  inputSize: 640,
});
