  • Patent number: 10699126
    Abstract: Techniques and systems are provided for performing object recognition for video frames. For example, one or more video frames of a first video are obtained. The one or more video frames have a first resolution and include one or more objects. The one or more objects are detected in the one or more video frames of the first video based on object detection being performed on the one or more video frames. One or more video frames of a second video are also obtained. The one or more video frames of the second video also include the one or more objects and have a second resolution that is greater than the first resolution. An object recognition process is performed on the one or more video frames of the second video to recognize or identify the one or more objects detected in the one or more video frames of the first video.

  • Patent number: 9083521
    Abstract: A system is provided for transmitting information through a speech codec (in-band) such as found in a wireless communication network. A modulator transforms the data into a spectrally noise-like signal based on the mapping of a shaped pulse to predetermined positions within a modulation frame, and the signal is efficiently encoded by a speech codec. A synchronization sequence provides modulation frame timing at the receiver and is detected based on analysis of a correlation peak pattern. A request/response protocol provides reliable transfer of data using message redundancy, retransmission, and/or robust modulation modes dependent on the communication channel conditions.

  • Patent number: 8660840
    Abstract: A method and apparatus for predictively quantizing voiced speech includes a parameter generator and a quantizer. The parameter generator is configured to extract parameters from frames of predictive speech such as voiced speech, and to transform the extracted information to a frequency-domain representation. The quantizer is configured to subtract a weighted sum of the parameters for previous frames from the parameter for the current frame. The quantizer is configured to quantize the difference value. A prototype extractor may be added to first extract a pitch period prototype to be processed by the parameter generator.

  • Patent number: 8527265
    Abstract: A scalable speech and audio codec is provided that implements combinatorial spectrum encoding. A residual signal is obtained from a Code Excited Linear Prediction (CELP)-based encoding layer, where the residual signal is a difference between an original audio signal and a reconstructed version of the original audio signal. The residual signal is transformed at a Discrete Cosine Transform (DCT)-type transform layer to obtain a corresponding transform spectrum having a plurality of spectral lines. The transform spectrum spectral lines are transformed using a combinatorial position coding technique. The combinatorial position coding technique includes generating a lexicographical index for a selected subset of spectral lines, where each lexicographic index represents one of a plurality of possible binary strings representing the positions of the selected subset of spectral lines. The lexicographical index represents non-zero spectral lines in a binary string in fewer bits than the length of the binary string.

  • Patent number: 8243695
    Abstract: A system and method for detection of rate determination algorithm errors in variable rate communications system receivers. The disclosed embodiments prevent rate determination algorithm errors from causing audible artifacts such as screeches or beeps. The disclosed system and method detects frames with incorrectly determined data rates and performs frame erasure processing and/or memory state clean up to prevent propagation of distortion across multiple frames. Frames with incorrectly determined data rates are detected by checking illegal rate transitions, reserved bits, validating unused filter type bit combinations and analyzing relationships between fixed code-book gains and linear prediction coefficient gains.

  • Publication number: 20100174539
    Abstract: A vector quantization codebook search method and apparatus use support vector machines (“SVMs”) to compute a hyperplane, where the hyperplane is used to separate codebook elements into a plurality of bins. During execution, a controller determines which of the plurality of bins contains a desired codebook element, and then searches the determined bin. Codebook search complexity is reduced and an exhaustive codebook search is selectively avoided.
