Each
TransformFeatureConfig describes only one aspect (TransformFeature) of a transform, meaning multiple can be applicable at the same time; for example, the "stop" hand gesture must satisfy both TransformFeature.FingersUp and TransformFeature.PalmAwayFromFace. A
TransformFeatureConfigList can thus be thought of as a list of requirements, all of which must be satisfied in order for the transform to be acceptable for recognition.
