Abstract

本申请实施例提供了一种帧间预测方法、编码器、解码器及存储介质，包括：确定当前块的预测模式参数；当预测模式参数指示使用GEO确定当前块的帧间预测时，确定当前块的GEO参数；根据GEO参数，确定第一预测值和第二预测值；根据GEO参数，确定当前块内像素点对应的权重索引；对当前块内像素点对应的权重索引分别进行嵌位处理，得到当前块内像素点对应的权重索引绝对信息；嵌位处理是将当前块内像素点对应的权重索引的绝对值的最大值嵌位至预设数值的一半；基于当前块内像素点对应的权重索引绝对信息，确定第一权重值和第二权重值；使用第一预测值、第一权重值、第二预测值和第二权重值，得到当前块的帧间预测值。
