Abstract: Systems and methods are directed to multiview format detection. A multiview image that comprises a plurality of tiled view images is accessed. A cross-correlation map from the multiview image may be generated by autocorrelating the multiview image with a shifted copy of the multiview image. The cross-correlation map may be sampled at a plurality of predefined locations of the cross-correlation map to identify a set of cross-correlation values. A multiview format of the multiview image may be detected by classifying a feature set of the multiview image that comprises the set of cross-correlation values. The multiview image may be configured to be rendered on a multiview display based on the multiview format.

Abstract: An adaptive background multiview image display system and method provides improved multiview image quality. Systems and methods may involve generating crosstalk data that reduces crosstalk between a first view of subject image and a second view of the subject image. The subject image may be a multiview image to be overlaid on a background image. A crosstalk violation may be detected in the subject image based on the crosstalk data. At least one of a color value or a brightness value of the background image is determined according to a degree of the crosstalk violation to generate the background image. The subject image may then be overlaid on the generated background image.
