Disclosed are a prediction method, an encoder, a decoder and a computer storage medium. The method is applied to an encoder. The method comprises: determining N neighbor nodes to be searched for that are of the current node; if there is a coplanar neighbor node that is coplanar with the current node and has been encoded among said N neighbor nodes, acquiring a first attribute reconstruction value of the coplanar neighbor node; if there is a collinear neighbor node that is collinear with the current node and has been encoded among said N neighbor nodes, acquiring a second attribute reconstruction value of the collinear neighbor node; and on the basis of the first attribute reconstruction value and/or the second attribute reconstruction value, determining an attribute prediction value of the current node. L'invention divulgue un procédé de prédiction, un codeur, un décodeur et un support de stockage informatique. Le procédé est appliqué à un codeur. Le procédé comprend les étapes consistant à : déterminer N nœu
