摘要

内部预测使用基于块的运动补偿从一个或多个先前编码的视频帧或字段创建预测模型。本文简要分析了h.264编码标准的基线配置文件中可用的互预测工具。与早期标准的重要区别包括支持一系列块大小(从16×16到4×4)和精细的子样本运动向量(亮度分量的四分之一样本分辨率)。

Brief analysis of inter prediction in video coding
Inter prediction creates a prediction model from one or more previously encoded video frames or fields using block-based motion compensation. In this paper, we briefly analyze the inter prediction tools available in the Baseline profile of the h.264 coding standard. Important differences from earlier standards include the support for a range of block sizes (from 16×16 down to 4×4) and fine sub-sample motion vectors (quarter-sample resolution in the luma component).
