  • Publication number: 20230368489
    Abstract: A method is provided for generating enhanced image data for display on different types of display platforms. The method can include receiving a first format of display image data mastered to be displayed on a first type of display system. The method can include receiving a second format of display image data mastered to be displayed on a second type of display system that is different than the first type of display system. The method can include detecting one or more corresponding pixels in image segments among the first format of display image data and the second format of display image data. The method can include using attributes from the one or more corresponding pixel to generate enhanced image data for display.

  • Patent number: 11544830
    Abstract: A digital image sequence with multiple image frames can be enhanced. An appearance graph can be determined from the digital image sequence. The appearance graph includes prime layer nodes. Each prime layer node can represent a distinctive visual style. A prime layer image sequence can be computed for each prime layer node that matches the visual style represented by the prime layer node. An enhanced image sequence can be generated by blending at least two prime layer image sequences as defined by the appearance graph.

  • Patent number: 9483812
    Abstract: Methods and systems for digitally enhancing the characteristics of an image sequence including video and motion picture images are provided. Highly accurate motion information represented by trajectories are generated through analyzing available image frames in the image sequence. Some embodiments of the present invention relate to generating multiple layer trajectories from an image sequence. Certain aspects may be applicable to the enhancement of three-dimensional (3D) image sequences including 3D video and 3D motion pictures.

  • Patent number: 9384535
    Abstract: Methods and systems for reducing or eliminating perceived ghosting in stereoscopic three-dimensional (3D) image display are described. A stereoscopic image that includes image content can be received. Display system parameters can be received. A local region of the stereoscopic image can be identified using the image content. The local region can include ghosting. Psychovisual factors can be selected using the image content. A modified stereoscopic image can be generated from the stereoscopic image by reducing or eliminating the ghosting of the local region using the psychovisual factors and the display system parameters. The modified stereoscopic image can be outputted for display.
