Resumen
Audio description is an accessibility feature designed to make visual information accessible to blind or low vision people. To increase the range of audio description tracks
in digital video applications, we propose a system for automatic audio description generation of videos. The system can use as source of information about the film the original
script or the video itself. As a proof of concept, we developed a prototype that automatically generates audio description based on actions taken from the script and objects
recognized in the video. The experiments contemplated the application of the solution in
fiction films and surveillance videos. For fiction films, an evaluation was made with blind
people. The results indicated that through the automatic audio description generated by
the solution, it was possible to provide contextual information that can help the user in
the general understanding of the story. For surveillance videos, a performance evaluation
was made using the delay time of each component. Results indicate that a solution has
the potential to be used in contexts that require real-time AD.
