摘要： A method determines distortion in a video by measuring a spatial distortion in coded frames, and by measuring a temporal distortion and spatial distortion in uncoded frames. The spatial distortion of the coded frames is combined with the temporal distortion and the spatial distortion of the uncoded frames to determine a total average distortion in the video.

摘要： A method estimates rate and distortion characteristics of a video object. First and second object shape features are respectively extracted at a first and second resolution of the video object. First and second rate distortion characteristics of the video object are respectively determined from the extracted first and second object shape features according to first and second modeling parameters. The extracted object shape features can be discrete, such as states of binary shape patterns of the video object, or the object shape features can be continuous such as a set of statistical moments representing a probability density function of the video object.

摘要： A method for reconstructing an incomplete signal in a sub-band transmission system is disclosed. Signal degradation from signal loss in a sub-band transmission system may be avoided by formulating an error function, and finding an optimal signal which minimizes the error between the sub-band signals interpolated from received sub-band signals and the sub-band signals obtained by convolving an optimal reconstructed signal with the original analysis filters. The minimized system equation is solved to provide an optimal reconstructed output signal.

摘要： An apparatus and method for measuring molecular diffusivity in porous powders or minerals, e.g., the microporous synthetic minerals used for gas separation and chemical catalysis, were invented that allows a varying pressure in the gas around the powder during the measurement. This obviates the need for the pressure to be constant and the attendant complicated component parts. A mass balance model equation of the sample cell with the diffusivity as an adjustable parameter is used to deduce the sample cell pressure change versus time (uptake curve) until the equilibration of gas diffusion into the powder. A numerical analysis method is used to solve the mathematical model to compute a simulated uptake curve. Curve fitting of the simulated and measured uptake curves is used to optimize the diffusivity parameter, which gives the measured diffusivity. The apparatus and method are simple, easy to use, and automation is also simple.

摘要： An example video encoder uses a self-adaptive dictionary that only depends on the block location, without requiring real time design/redesign of the dictionary. A mean-removed block may be directly represented using a redundant dictionary including all possible inter-prediction candidates with integer motion vectors (mean-removed). In general the dictionary may also contain some intra-prediction candidates and some pre-designed fixed dictionary atoms. The coefficients may be determined by minimizing the L0 norm of the coefficients subject to a constraint on the sparse approximation error. Using such a self-adaptive dictionary can lead to a very sparse representation, with significantly fewer non-zero coefficients than using the DCT transform on the prediction error. Some example embodiments consistent with the present invention use a modified orthogonal matching pursuit (“OMP”) algorithm to orthonormalize each new chosen atom with respect to all previously chosen and orthonormalized atoms. Each image block is represented by the quantized coefficients corresponding to the orthonormalized atoms.
摘要翻译：示例性视频编码器使用仅依赖于块位置的自适应字典，而不需要对字典进行实时设计/重新设计。可以使用包括具有整数运动向量（均值去除）的所有可能的帧间预测候选的冗余字典来直接表示平均去除块。通常，字典还可以包含一些帧内预测候选和一些预先设计的固定字典原子。可以通过使经受稀疏近似误差的约束的系数的L0范数最小化来确定系数。使用这样的自适应词典可以导致非常稀疏的表示，与对预测误差使用DCT变换相比，非零系数显着更少。与本发明一致的一些示例性实施例使用修改的正交匹配追踪（“OMP”）算法来相对于所有先前选择的和正交归一化的原子对每个新选择的原子进行正交校正。每个图像块由对应于正交归一化原子的量化系数表示。
