  • Publication number: 20190318207
    Abstract: In some implementations, an image classification system of an autonomous or semi-autonomous vehicle is capable of improving multi-object classification by reducing repeated incorrect classification of objects that are considered rarely occurring objects. The system can include a common instance classifier that is trained to identify and recognize general objects (e.g., commonly occurring objects and rarely occurring objects) as belonging to specified object categories, and a rare instance classifier that is trained to compute one or more rarity scores representing likelihoods that an input image is correctly classified by the common instance classifier. The output of the rare instance classifier can be used to adjust the classification output of the common instance classifier such that the likelihood of input images being incorrectly classified is reduced.

  • Patent number: 10422884
    Abstract: Methods and systems for performing Precise Point Positioning (PPP) ambiguity resolution using Global Navigation Satellite Systems (GNSS) triple frequency signals are described. In an embodiment, the method may include computing, using a processing device, an L1/L2 or L2/L5 wide-lane fractional bias model, in which the bias is split into one direction-independent and three direction-dependent bias components for each satellite. Additionally, the method may include resolving, using the processing device, PPP ambiguity using triple-frequency signals. The method may also include applying, using the processing device, a carrier smooth carrier function to resolve measurement noise. Resolving the PPP ambiguity may include fixing the L2/L5 wide-lane ambiguities in a geometry-free function. Additionally, resolving the PPP ambiguity may include fixing the L1/L2 wide-lane ambiguities in a geometry-based function.

  • Publication number: 20190246219
    Abstract: A method for controlling a controllable acoustic valve of a hearing device. The valve includes a moveable valve element adapted to be positioned in one of at least two essentially stable states. The moveable valve element is configured to be maintained in each of the essentially stable states by a retention force. A neutral point with essentially cancelling retention forces exists between the least two essentially stable states. The method includes providing a first drive signal to the controllable acoustic valve to overcome a retention force of a first essentially stable state in order to initiate movement of the moveable valve element from the first essentially stable state to a second essentially stable state. The provided first drive signal is capable of bringing the moveable valve element from the first essentially stable state and beyond a neutral point between the first and second essentially stable states.

  • Publication number: 20190237088
    Abstract: The quality of encoded signals can be improved by reclassifying AUDIO signals carrying non-speech data as VOICE signals when periodicity parameters of the signal satisfy one or more criteria. In some embodiments, only low or medium bit rate signals are considered for re-classification. The periodicity parameters can include any characteristic or set of characteristics indicative of periodicity. For example, the periodicity parameter may include pitch differences between subframes in the audio signal, a normalized pitch correlation for one or more subframes, an average normalized pitch correlation for the audio signal, or combinations thereof. Audio signals which are re-classified as VOICED signals may be encoded in the time-domain, while audio signals that remain classified as AUDIO signals may be encoded in the frequency-domain.

  • Patent number: 10347275
    Abstract: A method for speech processing includes determining a first unvoicing parameter for a first subframe of a speech signal, and determining a smoothed unvoicing parameter for the first subframe according to a second unvoicing parameter of a second subframe prior to the first subframe of the speech signal. The first unvoicing parameter is determined according to a periodicity parameter and a spectral tilt parameter. The method further includes computing a difference between the first unvoicing parameter for the first subframe and the smoothed unvoicing parameter for the first subframe and determining a classification of the first subframe using the computed difference as a decision parameter. The classification indicates whether the first subframe is an unvoiced speech signal or not an unvoiced speech signal. Bandwidth extension is performed on the speech signal for the first subframe according to the classification of the first subframe.

  • Patent number: 10339938
    Abstract: In accordance with an embodiment, a method of decoding an encoded audio bitstream at a decoder includes receiving the audio bitstream, decoding a low band bitstream of the audio bitstream to get low band coefficients in a frequency domain, and copying a plurality of the low band coefficients to a high frequency band location to generate high band coefficients. The method further includes processing the high band coefficients to form processed high band coefficients. Processing includes modifying an energy envelope of the high band coefficients by multiplying modification gains to flatten or smooth the high band coefficients, and applying a received spectral envelope decoded from the received audio bitstream to the high band coefficients. The low band coefficients and the processed high band coefficients are then inverse-transformed to the time domain to obtain a time domain output signal.

    Abstract: A method, a computer program product, and a system are provided for video based action recognition. The system includes a processor. One or more frames from one or more video sequences are received. A feature vector for each patch of the one or more frames is generated using a deep convolutional neural network. An attention factor for the feature vectors is generated based on a within-frame attention and a between-frame attention. A target action is identified using a multi-layer deep long short-term memory process applied to the attention factor, said target action representing at least one of the one or more video sequences. An operation of a processor-based machine is controlled to change a state of the processor-based machine, responsive to the at least one of the one or more video sequences including the identified target action.
