摘要： Classifying a series of quantized transform coefficients of a block of image data into one of a pre-defined plurality of classes for entropy coding, and entropy coding the block. A class is defined by at least the size of the block and typically but not necessarily one or more other factors. The classified series is coded by one of a set of pre-defined entropy coding methods, e.g., variable length coding methods for the pre-defined classes.

摘要： A coding method, apparatus, and storage media with instructions to carry out a method. The method operates on an ordered series of transform coefficients of a block of image data, and for a fixed quantization method, and includes quantizing and encoding the ordered series to form a coded bitstream. The quantizing and encoding uses one or more variable length code (VLC) mappings. The quantizing includes quantizing to have amplitude- 1 at least one coefficient that would be quantized by the fixed quantization method to have zero amplitude, quantizing to have zero amplitude at least one coefficient that would be quantized by the fixed quantization method to have amplitude- 1, and using the fixed quantization method to quantize any coefficient that is quantized by the fixed quantization method not to have zero amplitude, amplitude- 1, or amplitude- 2.

摘要： Particular embodiments generally relate to video insertion information insertion in a compressed bitstream. In one embodiment, a compressed bitstream of data is received. Video insertion information to be added to the bitstream is then determined. One or more macrob locks out of a plurality of macrob locks are determined in the compressed bitstream. The macroblocks are determined in the compressed domain and not the spatial domain. Information is selectively inserted for the video insertion information for the determined one or more macroblocks in the compressed bitstream. For example, encoded macroblocks for the video insertion information may replace the determined one or more macroblocks. Also, the one or more macroblocks may be decoded and information for the video insertion information is added to the decoded one or more macroblocks, and then the one or more macroblocks are re-encoded with the information. The re-encoded macroblocks may then replace the determined one or more macroblocks in the compressed bitstream.

The coding method includes encoding cluster of consecutive non-zero-valued coefficients, the encoding of a cluster including jointly encoding joint events that each are defined by at least two parameters: the number of zero-valued coefficients preceding the cluster, and the number of non-zero-valued coefficients in the cluster. The encoding of the cluster also includes encoding a parameter indicative of the number of amplitude-1 trailing non-zero-valued coefficients in the cluster, in one version with the parameter indicative of the number of trailing amplitude-1 coefficients part of the joint events such that the coding is according to a 3-dimensional joint variable length coding table. The method further includes encoding the amplitudes of the non-zero-valued coefficients that are not encoded by the joint encoding, e.g., encoding the amplitudes of the other than the trailing amplitude-1 coefficients.

摘要： Coding quantized transform coefficients as occur in image compression combines a position coding method to code the position of clusters of consecutive non-zero-value coefficients with an amplitude coding method to code the amplitudes of a concatenation of a plurality of the clusters. The amplitude coding method exploits that runs of amplitude 1 coefficients are more likely in the clusters than runs of other coefficient amplitudes.

摘要： A reservoir prediction system and method are provided that use generalized EnKF using kernels, capable of representing non-Gaussian random fields characterized by multi-point geostatistics. The main drawback of the standard EnKF is that the Kalman update essentially results in a linear combination of the forecasted ensemble, and the EnKF only uses the covariance and cross-covariance between the random fields (to be updated) and observations, thereby only preserving two-point statistics. Kernel methods allow the creation of nonlinear generalizations of linear algorithms that can be exclusively written in terms of dot products. By deriving the EnKF in a high-dimensional feature space implicitly defined using kernels, both the Kalman gain and update equations are nonlinearized, thus providing a completely general nonlinear set of EnKF equations, the nonlinearity being controlled by the kernel. By choosing high order polynomial kernels, multi-point statistics and therefore geological realism of the updated random fields can be preserved. The method is applied to two non-limiting examples where permeability is updated using production data as obserations, and is shown to better reproduce complex geology compared to the standard EnKF, while providing reasonable match to the production data.
摘要翻译：提供了一种使用内核的广义EnKF的能够表示以多点地质统计特征为特征的非高斯随机场的存储器预测系统和方法。标准EnKF的主要缺点是卡尔曼更新基本上导致了预测集合的线性组合，EnKF仅使用随机字段（待更新）和观察结果之间的协方差和互协方差，从而仅保留两个点统计。内核方法允许创建线性算法的非线性泛化，该算法可以专门用点积来写。通过在使用内核隐式定义的高维特征空间中导出EnKF，卡尔曼增益和更新方程都是非线性的，因此提供了一个完全一般的非线性EnKF方程组，非线性由内核控制。通过选择高阶多项式内核，可以保持多点统计，因此可以保留更新的随机场的地质现实性。该方法应用于两个非限制性实例，其中使用生产数据作为观测来更新渗透率，并且与标准EnKF相比，可以更好地复制复杂的地质，同时为生产数据提供合理的匹配。

摘要： A coding method, apparatus, and medium with software encoded thereon to implement a coding method. The coding method includes jointly encoding joint events that each are defined by a cluster of consecutive non-zero-valued coefficients, each joint event defined by three parameters: the number of zero-valued coefficients preceding the cluster, the number of non-zero-valued coefficients in the cluster, and an indication of which trailing coefficients up to a maximum number of M trailing coefficients have amplitude greater than 1, with the coding using a 3-dimensional joint VLC table. The method further includes encoding the amplitude of the non-zero-valued trailing coefficients that have amplitude greater than 1 encoding the amplitude of any remaining non-zero-valued coefficients in the clusters that have more than M non-zero-valued coefficients.

摘要： A method for variable length coding an ordered series of digital signals, e.g., of quantized transform coefficients of a block of image data with a most likely-to-occur amplitude, e.g., O, and at least one other amplitude, e.g., 1, to form a set of codewords. The method includes establishing a breakpoint (301) along the ordering to define a first contiguous region and a second contiguous region, such that clusters of consecutive signals of any value other than the most likely-to-occur value occur mostly in the first contiguous region. The method includes encoding the signals in the first region using a first region encoding method (303) suitable for encoding clusters; and encoding the signals in the second region using a second region encoding method (305). The first region and second region encoding methods include variable length codes such that relatively short codewords are formed to represent relatively more likely-to-occur sequences.
