Abstract: A signaling of at least one characteristic for layers of a multi-layered video signal such as, for example, for each layer the indication of dependent layers to which the respective layer directly relates via inter-layer prediction, or the signaling of the afore-mentioned second inter-dependency syntax structure, is described. A maximum syntax element is signaled within the multi-layered video signal to indicate a maximally used value of an extension layer-ID field of the packets of the multi-layered video signal, the scope of the maximum syntax element being, for example, a predetermined portion of the multi-layered video signal extending, for example, across several portions of the multi-layered video signal. Accordingly, it is feasible for devices such as decoders or network elements receiving the multi-layered video signal to gain, for a relatively large predetermined portion of the multi-layered video signal, knowledge about the actually consumed portion of the possible domain of possible values.

Abstract: A decoding method, system and storage medium are disclosed. In the method, a video decoder decodes a video from a bitstream of the video. The video decoder decodes, from the bitstream, an additional bit count M indicating a quantity of additional general constraints information (GCI) bits included in the bitstream. The additional bits include flag bits indicating respective additional coding tools to be constrained for the video, and an expected value of the additional bit count is 0, 6 or greater than 6. The decoder decodes M?6 bits that follow six flag bits in the bitstream in response to determining that the decoded additional bit count M is greater than 6. The decoder further decodes the remaining portion of the bitstream into images independent of the decoded M?6 bits and based, at least in part, upon constraints specified for the respective additional coding tools by the six flag bits.

Abstract: Described herein are methods and systems for obtaining high-quality images, which may be suitable for various applications such as training and operating artificial intelligence (AI) systems. Specifically, a system may comprise multiple cameras and one or more actuators that are capable of moving these cameras relative to each other. For example, these cameras may form one or more stereo pairs, each pair having its stereo axis. The actuators can change baselines in these pairs and/or tilt these stereo axes relative to the imaged objects to address possible self-similarity issues associated with the shape of these objects and their orientation relative to the cameras. In some examples, the simultaneous images captured by these cameras are used to construct a three-dimensional (3D) model. The fidelity of this model is then used to determine the position of the cameras (as a camera unit or individually for each camera).

Based on the changes in voltage or current supplied by the power supply, data embedded in the input light to the image intensifier tube is extracted.
