    Abstract: Systems and methods are directed to generating a three-dimensional (3D) model of a first image set. The first image set (e.g., input image set) corresponds to different viewing angles of an object that is subject to 3D modeling. A volumetric density function is generated from the first image set. A second image set (e.g., a textured image set) is generated from the volumetric density function and from a predefined color function. The first image set is blended with the second image set to generate a third image set (e.g., an image set with temporary textures). To generate the 3D model, a 3D surface model is generated from the third image set. In addition, a texture map of the 3D surface model is generated from the first image set. A computing system is configured to render the 3D surface model and texture map for display.

    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.
