Methods of encoding and decoding depth data are disclosed. In an encoding method, depth values and occupancy data are both encoded into a depth map. The method adapts how the depth values and occupancy data are converted to map values in the depth map. For example, it may adaptively select a threshold, above or below which all values represent unoccupied pixels. By adapting how the depth and occupancy are encoded, based on analysis of the depth values, the method can enable more effective encoding and transmission of the depth data and occupancy data. The encoding method outputs metadata defining the adaptive encoding. This metadata can be used by a corresponding decoding method, to decode the map values. Also provided are an encoder and a decoder for depth data, and a corresponding bitstream, comprising a depth map and its associated metadata.

The invention proposes a transmitter (such as a gateway or base station, both indoors and outdoors) that actively creates multiple virtual anchors which are associated with certain known reflectors by means of a code, to allow low-capability receivers to be localized more easily. By measuring propagation features, such as, e.g., timing of receipt, of three or more coded beams, low capability receivers—even those with only a single antenna—can be localized, e.g., by the transmitter or by the receivers themselves. The receivers might localize themselves if each beam includes e.g. the location of the anchors, the location of transmitter, and the sending time. This has the advantage that the receivers do not have to send any information back to the transmitter.

Abstract
Proposed are schemes, solutions, concepts, designs, methods and systems pertaining to aiding and/or improving image acquisition from a vibratory personal care device having an image capture device. Embodiments propose identifying a target part (e.g. low velocity/motion part) of the vibration cycle based on a sensed operating parameter of the personal care device, and then controlling the image capture device based on the identified target part of the vibration cycle. Through control of the image capture device according to a target part of the vibration cycle, improved images (e.g. images exhibiting less blur and/or distortion) may be obtained. In this way, improved images may be obtained from a vibratory personal care device.

Abstract
Proposed are schemes, solutions, concepts, designs, methods and systems pertaining to aiding and/or improving image acquisition from a vibratory personal care device having a camera. Embodiments propose identifying image data captured during a target part (e.g. low velocity/motion part) of the vibration cycle based on an edge quality value of the image data. Using the identified image data, an image of improved quality may then be constructed. Thus, through adaptation of image data acquisition according to edge quality of image data, improved images (e.g. images exhibiting less blur and/or distortion) may be constructed/generated.
