Abstract
一种预测值的确定方法、编码器、解码器以及计算机存储介质，该方法应用于编码器，包括：获取当前块相邻像素的重建值(S501)，对相邻像素的重建值进行滤波处理，得到当前块的参考值集(S502)，当当前块的大小小于预设的阈值时，根据当前块中像素亮度分量的比特深度的取值，计算第一常数的取值(S503)，确定预测输入值集中的第一个预测输入值为第一常数的取值与参考值集中的第一个参考值的差值(S504)，根据参考值集，确定预测输入值集中除第一个预测输入值外的其他预测输入值(S505)，根据预测输入值集，计算当前块中特定位置像素的预测值(S506)，对特定位置像素的预测值进行滤波处理，得到当前块中全部像素的预测值(S507)。
