摘要： An adaptive filter is applied (160) to samples in an initial pattern of samples. The samples in the initial pattern correspond to a subset of the image pixels which are to be predicted using the samples. A level value of each sample in the pattern is varied (165). The level value corresponds to the intensity/signal value of the sample, and may have a strong effect on the prediction power of the samples. A first prediction pattern (i.e., the prediction signal corresponding to the sampling pattern) is generated from the samples. A sample movement process is performed (170) on a current sample in the first prediction pattern to change a current position of the current sample in the first prediction pattern. A local prediction of pixels influenced by the sample is updated if the sample's position is changed. A sample removal process is performed (175) on the current sample to remove the sample from the first pattern if a criteria is satisfied. A local prediction of pixels is updated if the current sample is removed. A second prediction pattern (i.e., the prediction signal corresponding to the new/second sampling pattern) is generated from the samples remaining in the first pattern. The second pattern is output.

摘要： An initial decimation filter is applied to an original frame to generate a decimated frame. An optimized prediction filter is extracted from both the decimated frame and the original frame, while the initial decimation filter is held fixed. A predicted from is generated from the optimized prediction filter and the decimated frame, and an optimize decimation filter is extracted from the decimated frame and the predicted frame, while the optimized prediction filter remains fixed.

摘要翻译： 在样本的初始模式中对自适应滤波器（160）进行采样。 初始图案中的样本对应于将使用样本预测的图像像素的子集。 图案中每个样品的水平值变化（165）。 电平值对应于样品的强度/信号值，并且可能对样品的预测功率有很强的影响。 从样本生成第一预测图案（即，对应于采样图案的预测信号）。 对第一预测图案中的当前样本进行样本移动处理（170），以改变第一预测图案中的当前样本的当前位置。 如果样本的位置发生变化，则会更新受样本影响的像素的局部预测。 如果满足标准，则在当前样品上执行样品去除过程（175）以从第一图案中移除样品。 如果删除当前样本，则更新像素的局部预测。 从保留在第一图案中的样本生成第二预测图案（即，对应于新/第二采样图案的预测信号）。 输出第二个模式。

摘要： Multi-field taps are defined based on a decimated field. The multi-field taps are used to generate correlation matrices, the elements of which are used to generate covariance matrices. A principal component space is obtained by projecting the correlation matrix elements on to eigenvectors. The principal component space is partitioned into classes and a least square filter set is generated for each class.
