Abstract:
Methods and systems for automatically evaluating an audio description track of a media asset include initializing a rating of an audio description track of a media asset to a default value; receiving a first video frame and a second video frame of the media asset; detecting an object in the first video frame and the second video frame; determining that a difference in a characteristic of the object between the first video frame and the second video frame exceeds a threshold difference; determining that an audio characteristic in a portion of the audio description track that corresponds to the first video frame and the second video frame exceeds a threshold audio characteristic; and increasing the rating of the audio description track by a unit.
