Abstract
一种图像分量预测方法、装置及计算机存储介质,该方法包括:获取视频图像中编码块的待预测图像分量对应的N个相邻参考像素点(S801),N个相邻参考像素点为与所述编码块相邻的参考像素点,N为预设的整数值;计算所述N个相邻参考像素点的均值,得到第一均值点(S802);通过第一均值点对第二参考像素集合进行分组,得到第一参考像素子集和第二参考像素子集(S803);基于第一参考像素子集和第二参考像素子集,确定两个拟合点(S804);基于两个拟合点确定模型参数,根据所述模型参数得到待预测图像分量对应的预测模型;其中,所述预测模型用于实现对待预测图像分量的预测处理,以得到所述待预测图像分量对应的预测值(S805)。
