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第一参考像素集合(S501)；当所述第一参考像素集合中有效像素点个数小于预设个数时，将预设分量值作为所述待预测图像分量对应的预测值(S502)；当所述第一参考像素集合中有效像素点个数大于或等于预设个数时，对所述第一参考像素集合进行筛选，得到第二参考像素集合(S503)；当所述第二参考像素集合中有效像素点个数小于预设个数时，将预设分量值作为所述待预测图像分量对应的预测值(S504)；当所述第二参考像素集合中有效像素点个数等于预设个数时，通过所述第二参考像素集合确定模型参数，并根据所述模型参数得到所述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所述待预测图像分量的预测处理，以得到待预测图像分量对应的预测值(S505)。
