  • Patent number: 12063376
    Abstract: A Local illumination compensation system for video encoding and decoding uses memory for storing illumination compensation parameters and does not require access to reconstructed pixels of neighboring blocks. A set of illumination compensation parameters is stored in a dedicated buffer, which is of limited size, and which is decoupled from the coding unit level storage of information. The buffer contains a set of illumination compensation parameters, which may be, for example, computed (or determined in some other manner) on the fly or determined beforehand (for example for example obtained from the video signal or from a device).

  • Patent number: 12052418
    Abstract: A method for encoding a block is disclosed. To this aim, a split mode is determined based on a rate-distortion optimization using a texture-based split prediction set obtained for the block. As an example, the split mode is determined by adapting the texture-based split prediction set according to at least one of a binary or triple split mode non-redundancy constraint or a heuristic-based split mode set pruning. The block is finally encoded using the determined split mode.

  • Patent number: 12032740
    Abstract: In example embodiments, a method includes obtaining a first measurement of at least a first physiological parameter of a user from a time before presentation of an information item to the user. The information item may be, for example, a notification, an advertisement, or an emergency alert, among other possibilities. A second measurement of the first physiological parameter is obtained from a time after a beginning of the presentation of the information item to the user (e.g. during the presentation). Based at least on a comparison between the first and second measurements, a determination is made of whether the user has perceived the information item. The determination may also be based on a corruption coefficient indicating an amount by which an activity of the user is likely to interfere with the first physiological parameter.

  • Publication number: 20240223761
    Abstract: An image is split into a plurality of blocks of various sizes and a subdivision level counter is associated to each of the blocks. The value of this subdivision level counter for a block is representative of the size of the block and is used to determine the quantization parameter for the block. The value is propagated for each subdivision and incremented according the type of the subdivision. When the image is split, an analysis is done according to the subdivision level counter, a maximal value of subdivision and the type of split, in order to determine the start of a new quantization group and when it is the case, the current position of the partition is propagated to the further split partitions to be stored with these partition and serve in the prediction process when decoding.

  • Patent number: 12008154
    Abstract: Program actions may be initiated after detection of a predefined gesture by a user with a real-world object. Users may interact with their physical environment in an augmented reality by detecting interactions with real objects using a combination of location and motion detection, material identification using wearable sensors, or both. Based on detected sensor data from user interaction with a real-world object, a predefined gesture may be identified and a program action associated with that target interaction for the real-world object may be executed. In some cases, the user experience may be enhanced by providing haptic feedback in response to tactile gestures and resulting events.

  • Patent number: 12008776
    Abstract: For multi-view video content represented in the MVD (Multi-view+Depth) format, the depth maps may be processed to improve the coherency therebetween. In one implementation, to process a target view based on an input view, pixels of the input view are first projected into the world coordinate system, then into the target view to form a projected view. The texture of the projected view and the texture of the target view are compared. If the difference at a pixel is small, then the depth of the target view at that pixel is adjusted, for example, replaced by the corresponding depth of the projected view. When the multi-view video content is encoded and decoded in a system, depth map processing may be applied in the pre-processing and post-processing modules to improve video compression efficiency and the rendering quality.

  • Patent number: 11995578
    Abstract: Systems and methods are described for improved color rendering. In some embodiments, video is captured of a real-world scene, and a region of screen content is detected in the captured video. A processor selectively applies a screen-content color transformation on the region of screen content to generate processed video, and the processed video is displayed substantially in real time, for example on a video-see-through head-mounted display. The screen-content color processing may be different for different types of external displays. The screen-content color processing may also be determined based at least in part on illumination conditions. In some embodiments, the color of displayed virtual objects is adjusted based on visual parameters of the screen content.
