摘要：
Reference processing may be used in a video encoder or decoder to derive reference pictures that are better correlated with a source image to be encoded or decoded, which generally yields better coding efficiency. Methods for filter selection for a reference processing unit adapted for use in a video codec system are discussed. Specifically, methods for filter selection based on performing motion estimation and obtaining distortion/cost information by comparing reference pictures, either processed or non-processed, with the source image to be encoded are discussed.
摘要（中）：
可以在视频编码器或解码器中使用参考处理来导出与要编码或解码的源图像更好相关的参考图像，这通常产生更好的编码效率。 讨论了适用于视频编解码系统的参考处理单元的滤波器选择方法。 具体地，讨论了基于执行运动估计的滤波器选择的方法，并且通过将被处理或未处理的参考图像与待编码的源图像进行比较来获得失真/成本信息。
