  • Publication number: 20240105205
    Abstract: A method of matching a voice for each object included in a video, includes: separating a plurality of voices in a video; determining a dissimilarity between the plurality of voices; selecting a partial duration in an entire duration of the video as a matching duration, based on the dissimilarity between the plurality of voices; matching, within the matching duration, the plurality of voices with a plurality of objects in the video respectively, based on mouth movements of the plurality of objects; and matching the plurality of voices with the plurality of objects respectively in the entire duration of the video, based on results of the matching between the plurality of voices and the plurality of objects within the matching duration.

  • Patent number: 11176877
    Abstract: An image display apparatus is disclosed. The image display apparatus includes a panel configured to display an image, a backlight including a plurality of light sources configured to output light to the panel, a light source driver configured to drive the plurality of light sources, and a processor configured to control the light source driver, wherein the processor changes the turn on duty of a light source corresponding to a moving object area in an input image and changes the level of current flowing in the light source. Consequently, the definition and luminance of an image including a moving object may be improved.
