Q: How to serialize/unserialize FullFaceDescriptions?

[salamanders]

Detecting faces is great, but can be slow. I'd like to save the detections to an IndexDB and do some math on them when all are completed.

Is there a standard/easy way to do this? I've got a Dexie hacky way with

db.addFace = async function(imageName, tileLocation, ffd) {
  return await db.faces.add({
    'image_name':imageName,
    'tile_x':tileLocation.x,
    'tile_y':tileLocation.y,
    'x':ffd.detection.box.x,
    'y':ffd.detection.box.y,
    'w':ffd.detection.box.width,
    'h':ffd.detection.box.height,
    'score':ffd.detection.score,
    'descriptor':ffd.descriptor,
    'landmarks': ffd.landmarks,
    'expressions': ffd.expressions
  });
};

that I'm sure is a bad idea.

It's not necessarely a bad idea, if you deserialize them correctly. Currently there is no easy way to do it, but I am happy to take PRs for implementing toJSON, fromJSON methods for all the helper classes.
