Description

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.

Contributor guide

Research direction
Check if the library provides any serialization methods for FullFaceDescriptions. Alternatively, implement JSON serialization by converting detection, landmark, and descriptor data to JSON compatible objects.
