Research direction

Start by reviewing the shape-detection API proposal and the detected-result definition, then trace how face detections are represented. Determine whether a confidence value can be specified consistently for the two described use cases; done means the proposal has an agreed result shape and behavior for exposing that information.

Description

enhancement

I havn't found any way to estimate the accuracy of the result provided by the API. It may be interesting for the application to have a confidence factor from the underlying technology.

the browser tell me there is a face here, but is it sure at 50% or 99% ? this may be useful for the application to know this information.

usecase 1: for example the app previously detected a face close to this location in a previous frame, so if the new detection is 50%, it is good enougth.

usecase 2: the application is doing a initial detection wihtout previous knowledge. So the API has to be real sure. So, for example, the app would require a 90% confidence.
