    Abstract: An efficient adaptive seismic data flow lossless compression and decompression method, which aims at solving the problem that data occupies the storage space and affects the transmission efficiency and is used for efficiently compressing geophysical instrument data, particularly seismic data after 24-bit analog-to-digital conversion. In the method, a data flow is compressed in a lossless mode in real time, and sampling data is adaptively compressed into 1 byte or 2 bytes or 3 bytes from original 24 bits and 3 bytes in a coding manner. Besides the foregoing data ranges, other integers that can be expressed by other 24-bit integer data with symbols are required to be expressed by 4 bytes after being operated through a compression algorithm.

  • Patent number: 9532069
    Abstract: Systems and methods of improving video encoding/decoding efficiency may be provided. A feature-based processing stream is applied to video data having a series of video frames. Computer-vision-based feature and object detection algorithms identify regions of interest throughout the video datacube. The detected features and objects are modeled with a compact set of parameters, and similar feature/object instances are associated across frames. Associated features/objects are formed into tracks, and each track is given a representative, characteristic feature. Similar characteristic features are clustered and then stored in a model library, for reuse in the compression of other videos. A model-based compression framework makes use of the preserved model data by detecting features in a new video to be encoded, relating those features to specific blocks of data, and accessing similar model information from the model library.

  • Patent number: 9406305
    Abstract: A message is communicated between devices by passing a host signal, such as an audio signal, with the message written into the spectrogram of the host signal. For host audio signals, the message is authored, converted to an image format (if not already in suitable image form) and written into the spectrogram of the audio signal. The resulting audio signal can be communicated in a variety of ways, but in one particular embodiment, the audio signal is played from a speaker (e.g., of a sending mobile device) and captured through the microphone of a receiving device. The spectrogram of the received audio signal is computed and then rendered to a display screen (e.g., the display of a receiving mobile device).

  • Patent number: 9392294
    Abstract: Color image data is compressed by determining the number of colors within a cell of an input image, each cell comprising an N×M array of pixels; in response to determining that the number of colors is greater than a first predetermined threshold, compress the cell using lossy compression; and in response to determining that the number of colors is less than the first predetermined threshold, reduce the number of colors.

  • Patent number: 9319703
    Abstract: A video encoder signals, in an encoded video bitstream, a video parameter set (VPS) that includes a plurality of Hypothetical Reference Decoder (HRD) parameter syntax structures that each include HRD parameters. For each respective HRD parameter syntax structure in the plurality of HRD parameter syntax structures, the VPS further includes a syntax element indicating whether the HRD parameters of the respective HRD parameter syntax structure include a common set of HRD parameters in addition to a set of sub-layer-specific HRD parameter information specific to a particular sub-layer of the encoded video bitstream. The common set of HRD parameters is common to all sub-layers of the encoded video bitstream. A video decoder or other device decodes, from the encoded video bitstream, the VPS and performs an operation using the HRD parameters of at least one of the HRD parameter syntax structures.

  • Patent number: 9269127
    Abstract: A hybrid filtering method called Karhunen Loeve Transform-Wavelet (KW) filtering is presented to de-noise dynamic cardiac magnetic resonance images that simultaneously takes advantage of the intrinsic spatial and temporal redundancies of real-time cardiac cine. This filtering technique combines a temporal Karhunen-Loeve transform (KLT) and spatial adaptive wavelet filtering. KW filtering has four steps. The first is applying the KLT along the temporal direction, generating a series of “eigenimages”. The second is applying Marcenko-Pastur (MP) law to identify and discard the noise-only eigenimages. The third applying a 2-D spatial wavelet filter with adaptive threshold to each eigenimage to define the wavelet filter strength for each of the eigenimages based on the noise variance and standard deviation of the signal. Lastly, the inverse KLT is applied to the filtered eigenimages to generate a new series of cine images with reduced image noise.

  • Patent number: 9253467
    Abstract: The present invention relates to correcting errors of multiple stream-based 3D images. The present invention comprises a 3D image synchronizing unit which synchronizes a first image and a second image consisting the 3D image; a 3D image correcting unit which detects an error block in the first image, searches a corresponding block in the second image, and corrects the error block on the basis of the block information of said corresponding block; and a compositing unit which composites the corrected first image and the second image to generate a 3D stereoscopic image. According to the present invention, bit errors occurring when transmitting multiple stream of 3D image can be corrected, providing better quality of 3D images. Also, error correction can be easily performed by using the method of the present invention without complicated calculations.

  • Patent number: 8942259
    Abstract: One embodiment of the present invention uses an abbreviated blanking period, in comparison to the standard VESA and CEA-EIA blanking periods, in order to send data, including low bandwidth, non-timing information, over one or more channels of the digital video link. By shortening the blanking period, the amount of time available for sending data in each scan line is increased, enabling the system to send more data over each channel. The inactive video portion of a scan line sent during vertical sync may also be used to send additional digital data. Shortening the blanking periods and/or using the inactive video sections of the horizontal scan lines adds to the overall data capacity of the link and may be used to send other digital data, such as multichannel audio, video, control, timing, closed captioning or other digital data.

    Abstract: A scoreboard for a video processor may keep track of only dispatched threads which have not yet completed execution. A first thread may itself snoop for execution of a second thread that must be executed before the first thread's execution. Thread execution may be freely reordered, subject only to the rule that a second thread, whose execution is dependent on execution of a first thread, can only be executed after the first thread.
