Encoding device for encoding vibrotactile multichannel signals, includes an encoder input module configured to receive a multichannel signal; a transform module adapted to execute a discrete wavelet transform of each channel of the multichannel signal and to generate a respective frequency range representation of each channel; a psychohaptic model unit designed to allocate to each channel, based on the respective frequency range representation, a mathematical representation of human perception of the channel; a clustering module configured to group, based on the allocated mathematical representation and a similarity measure of the channels, the wavelet-transformed channels of each multichannel signal into clusters, wherein each cluster is allocated a reference channel; a reference encoding module designed to quantize and compress wavelet coefficients of the reference channels which result from the performed discrete wavelet transform of the reference channels; a differential encoding module configured to encode the channels within a cluster, which are not a reference channel, in relation to the reference channel or at least one other channel of the cluster; and an encoder output module which outputs the clustered, compressed channels of each multichannel signal as a bit stream.

Encoding device and encoding method for multichannel encoding of vibrotactile signals and decoding and decoding method

There is provided a visual localization method comprising: (a) transmitting data representative of one or more detected visual features from a mobile device to a server; (b) estimating the location of the mobile device at the server based on the visual features received from the mobile device; (c) transmitting reference data associated with the estimated location from the server to the mobile device; and (d) the mobile device determining its location based on the reference data received from the server.

Visual localization method

The present disclosure relates to image modification such as an image enhancement. The image enhancement may be applied for any image modification and it may be applied during or after image encoding and/or decoding, e.g. as a loop filter or a post filter. In particular, the image modification includes a multi-channel processing in which a primary channel is processed separately and secondary channels are processed based on the processed primary channel. The processing is based on a neural network. In order to enhance the image modification performance, prior to applying the modification, the image channels are analyzed and a primary channel and the secondary channels are determined, which may vary for multiples of images, images or image areas.

Adaptive image enhancement using inter-channel correlation information

In an embodiment of the invention there is provided a method of visual localization, comprising: generating a plurality of virtual views, wherein each of the virtual views is associated with a location; obtaining a query image; determining the location where the query image was obtained on the basis of a comparison of the query image with said virtual views.

Visual localization

A method for determining the joint positions of a kinematic chain uses only an imaging sensor and a computing unit. Characteristic features on the links and joints of the kinematic chain are identified and the joint positions are calculated from these visual measurements. The robot can be controlled without the use of joint encoders. A sensor system for monitoring the status of a kinematic chain includes a computing unit and an imaging sensor. The imaging sensor may be mounted to the kinematic chain or in the surroundings of the kinematic chain and monitors the kinematic chain and/or the surroundings of the kinematic chain. The computing unit determines a pose and/or movement parameters of at least one element of the kinematic chain by analyzing an output signal of the imaging sensor, in particular by analyzing characteristic features and determines a rotational joint position by analyzing the characteristic features.

An encoding apparatus for encoding a vibrotactile signal includes a first transforming unit configured to perform a discrete wavelet transform of the signal, a second transforming unit configured to generate a frequency domain representation of the signal, a psychohaptic model unit configured to generate at least one quantization control signal based on the generated frequency domain representation of the sampled signal and on a predetermined perceptual model based on human haptic perception, a quantization unit configured to quantize wavelet coefficients resulting from the performed discrete wavelet transform and adapted by the quantization control signal, a compression unit configured to compress the quantized wavelet coefficients, and a bitstream generating unit configured to generate a bitstream corresponding to the encoded signal based on the compressed quantized wavelet coefficients. The subject matter described herein also includes a corresponding decoding unit, an encoding method and a decoding method.
