  • Publication number: 20150100189
    Abstract: A vehicle system includes at least one autonomous driving sensor that detects a location of a target vehicle, a communication device that receives infrastructure information from an infrastructure device, and a processing device that controls operation of at least one vehicle subsystem according to the infrastructure information. An exemplary method includes determining a location of a target vehicle, receiving infrastructure information from an infrastructure device, and controlling operation of at least one vehicle subsystem according to the infrastructure information.

  • Patent number: 8194915
    Abstract: A wavelet domain watermark encoder and decoder embed and detect auxiliary signals in a media signal, such as a still image, video or audio signal. The watermark encoders and decoders employ techniques that take advantage of processing plural levels of resolution of the signal to embed and detect auxiliary information in the media signal.

  • Patent number: 7319775
    Abstract: A wavelet domain watermark encoder and decoder embed and detect auxiliary signals in a media signal, such as a still image, video or audio signal. A watermark orientation signal is embedded in a wavelet decomposed signal to facilitate detection of the watermark in a geometrically distorted version of the embedded signal. In some configurations, the watermark signal forms a pattern in a transform domain used to perform synchronization of the watermark. The pattern has attributes used to determine orientation of the watermark in a geometrically distorted version of the media signal. The attributes carry two or more auxiliary message symbols in the watermark, and the attributes both carry the two or more auxiliary message symbols and form the pattern used to perform synchronization of the watermark.

  • Patent number: 7313250
    Abstract: The present invention is a digital watermarking technique Phasemark™ for image authentication. Using a signature extracted from the original image, the present invention hides an encoded version of the signature back into the original image, forming the watermarked image. The hiding is done in the frequency domain. Specifically, the present invention is a new transform domain digital watermarking technique that hides a signature obtained from the Fourier phases into the magnitude spectrum of the same host image. The detection process computes the discrete Fourier transform of the watermarked image, extracts and decodes the embedded signature, and then correlates it with calculated phase information. Correlation metrics determine the degree of authenticity of the image.

  • Patent number: 6968266
    Abstract: A control system 20 for an automotive vehicle 22, such as an adaptive cruise control (ACC) system, is provided including a controller 24. The controller 24 is electrically coupled to a radar system and a navigation system. The detection system 28 detects an object and generates an object profile. The navigation system 34 generates a navigation signal. The controller 24 in response to the object profile and the navigation signal, generates a predicted future path profile and inhibits resume speed of the vehicle 22 in response to the predicted future path profile. An additional feature of the invention is that the controller 24 may also be electrically coupled to a yaw rate sensor 30. The yaw rate sensor 30 senses the yaw rate of the vehicle 22 and generates a yaw rate signal. The controller 24 in response to the yaw rate signal inhibits resume speed of the vehicle 22.

  • Patent number: 6771797
    Abstract: The invention provides methods and systems for detecting and characterizing alterations of media content, such as images, video and audio signals, using watermark messages to carry signal metrics. By comparing signal metrics extracted from the watermark to signal metrics calculated from a suspect signal, a watermark decoder can detect and even classify types of alterations to the watermarked signal.
