Open the CIPO recordAbstract From the Canadian patent
Faces of speakers in a meeting or conference are automatically detected and facial images corresponding to each speaker are stored in a faces database. A timeline is created to graphically identify when each speaker is speaking during playback of a recording of the meeting. Instead of generically identifying each speaker in the timeline a facial image is shown to identify each speaker associated with the timeline.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
