摘要： Standard video compression techniques apply motion-compensated prediction combined with transform coding of the prediction error. In the context of prediction with fractional-pel motion vector resolution it was shown, that aliasing components contained in an image signal are limiting the prediction efficiency obtained by motion compensation. In order to consider aliasing, quantization and motion estimation errors, camera noise, etc., we analytically developed a twodimensional (2D) non-separable interpolation filter, which is independently calculated for each frame by minimizing the prediction error energy. For every fractional-pel position to be interpolated, an individual set of 2D filter coefficients is determined. Since transmitting filter coefficients as side information results in an additional bit rate, which is almost constant for different image resolutions and total bit rates, the loss in coding gain increases when total bit rates sink. Therefore, we developed an algorithm, which regards the non-separable two-dimensional filter as a polyphase filter. For each frame, predicting the interpolation filter impulse response through evaluation of the polyphase filter, we only have to encode the prediction error of the filter coefficients.

摘要翻译：标准视频压缩技术应用运动补偿预测与预测误差的变换编码相结合。在分数像素运动矢量分辨率的预测的上下文中，显示了包含在图像信号中的混叠分量限制了通过运动补偿获得的预测效率。为了考虑混叠，量化和运动估计误差，摄像机噪声等，我们分析开发了一种二维（2D）不可分离内插滤波器，通过最小化预测误差能量对每帧进行独立计算。对于要插值的每个小数像素位置，确定一组二维滤波器系数。由于发送滤波器系数作为侧信息导致附加比特率，其对于不同的图像分辨率和总比特率几乎是恒定的，所以当总比特率下降时，编码增益的损失增加。因此，我们开发了一种将不可分离的二维滤波器作为多相滤波器的算法。对于每个帧，通过评估多相滤波器来预测内插滤波器脉冲响应，我们只需要对滤波器系数的预测误差进行编码。

摘要： The transfer function of the communication channel in a mud pulse telemetry system is determined by sending a known signal through the channel and spectral analysis of the received signal. The known signal may be a chirp signal or a stepped frequency signal. Based on the determined transfer function, operating parameters of the pulser are adjusted.
