/**
 * Model parameters for MediaPipeFaceDetector TFJS runtime.
 *
 * `runtime`: Must set to be 'tfjs'.
 *
 * `modelType`: Optional. Possible values: 'short'|'full'. Defaults to
 * 'short'. The short-range model that works best for faces within 2 meters from
 * the camera, while the full-range model works best for faces within 5 meters.
 * For the full-range option, a sparse model is used for its improved inference
 * speed.
 *
 * `maxFaces`: Optional. Default to 1. The maximum number of faces that will
 * be detected by the model. The number of returned faces can be less than the
 * maximum (for example when no faces are present in the input).
 *
 * `detectorModelUrl`: Optional. An optional string that specifies custom url of
 * the detector model. This is useful for area/countries that don't have access
 * to the model hosted on tf.hub.
