摘要： Systems, methods, and instrumentalities are disclosed for adapting media (e.g., video) processing operations and/or parameters based on one or more viewing conditions in a media environment (e.g., to achieve power saving). Such viewing conditions may include a distance between a display device and a viewer, a viewpoint or viewing direction of the viewer towards the display device, and/or an ambient light level in the media environment. Aspects of the medical processing that may be adapted based on the viewing conditions may be associated with deblocking, sample adaptive offset (SAO) filtering, adaptive loop filtering (ALF), cross component adaptive loop filtering (CCALF), motion compensation, post-inter prediction processing, bi-prediction, residual scaling, luma mapping, chroma residual scaling (LMCS), geometric block partitioning, HDR signal reconstruction, etc.

摘要： A method for adapting the security settings of a communication station (12) depending on a security relevant event is disclosed, wherein the communication station (12) comprises a mobile terminal (16) with an identification module (18). In a first step, the security relevant event occurring in said communication station and/or said mobile terminal (16) is identified in an event handler (26, 261, 262, 27) and stored in an event registry (28). In a second step, a security registry (30) in the identification module (18) is updated according to the identified event. In a third step, the security level of the communication station (12) and/or the mobile terminal (16) is adapted according to the security registry (30) of the identification module (18). The invention also relates to a communication station (12) and to an identification module (18).

摘要： At least one embodiment relates to a method and apparatus for encoding a volumetric video representing a scene, said encoding being based on patches representing the color and depth of a 2D projection of subparts of the scene, wherein a first patch is packed in a second patch for a given time interval lower than or equal to a time period along which the second patch is defined when said first patch can be packed in said second patch over said time interval. Decoding method and apparatus are also provided.

摘要： Methods and apparatuses for encoding or decoding an image or a video based on neural network are provided. In an embodiment, an image is encoded by obtaining a first latent representation of the image in a first latent space, for instance from a Generative Adversarial Network. A second latent representation of the image in a second latent is obtained from the first latent representation and encoded. In an embodiment, the second latent space is obtained from an unfolding of the first latent space based on at least one constraint. In an embodiment, the second latent space is obtained using a neural network. The methods or apparatuses can be used for image editing and/or image or video coding.

摘要： In example embodiments, an apparatus includes a waveguide having an in-coupler an out-coupler. The waveguide has a first surface and an opposite second surface, and the waveguide provides at least one optical path from the in-coupler to the out-coupler. The in-coupler comprises a first diffraction grating with a first grating vector on the first surface and a second diffraction grating with a second grating vector on the second surface. At least one of the first and second grating vectors is not oriented along any of the optical paths from the in-coupler to the out-coupler. The second grating may alter the polarization state of in-coupled light and/or change the direction of the in-coupled light to aid in preventing the light from being out-coupled by the first diffraction grating.

摘要： A device (200) is proposed comprising a first part (101) of a first material having a first refractive index n1 and a second part (102) of a second material having a second refractive index n2 higher than n1. Such device further comprises at least one contact area (110) in between the first and second parts, radiating an outgoing electromagnetic wave (100o) when the device is illuminated by an incoming electromagnetic wave (100i). A projection of the at least one contact area along a direction of propagation of the incoming electromagnetic wave has a non-vanishing height lower than 1.2 times a critical height equal to a wavelength in vacuum of the incoming electromagnetic wave divided by the difference between the second refractive index n2 and the first refractive index n1.

摘要： A device applies a pre-function to an input signal to obtain an intermediate signal, wherein the pre-function has a linear section part of the input range. The device then applies a LUT including LUT entries that define a linear section and that delimit the range of the intermediate signal that corresponds to the part of the input range, resulting in an output signal that can be linearly processed through the pre-function and the LUT. The device can process a signal with positive and negative values, where one of these lies in the part of the input range that results in linear processing.
