Abstract

本申请实施例公开了一种图像预测方法、编码器、解码器以及存储介质，该方法包括：确定当前块的基于矩阵的帧内预测模式MIP输入采样矩阵；根据MIP输入采样矩阵，计算当前块的MIP预测块；根据当前块的参数，对MIP预测块进行第一滤波处理，得到第一滤波预测块，其中，第一滤波处理包括第一上采样处理，第一上采样处理表示对MIP预测块进行水平方向上采样后再进行垂直方向上采样得到第一上采样块，对MIP预测块进行垂直方向上采样后再进行水平方向上采样得到第二上采样块，将第一上采样块和第二上采样块的加权均值作为第一滤波预测块；将第一滤波预测块设置为当前块的帧内预测块；其中，帧内预测块包含当前块中全部像素位置的预测采样值。
