Abstract
Modalidades de esta solicitud describen un método y aparato de codificación de datos de imagen y un método y aparato de decodificación de datos de imagen, y se refiere al campo de procesamiento de imágenes, para resolver un problema de complejidad de codificación relativamente alta. El método de decodificación incluye: obtener un flujo de bits que incluye datos de imagen; analizar el flujo de bits para obtener información de modo de división de nodo de un árbol de codificación de primer nivel e información de modo de división de nodo de un árbol de codificación de segundo nivel, donde la información de modo de división de nodo del árbol de codificación de segundo nivel indica un modo de división que corresponde a un primer nodo del árbol de codificación de segundo nivel, el modo de división que corresponde al primer nodo es un modo en un conjunto de modos de división candidatos que corresponde al primer nodo y que se determina de acuerdo con una primera condición de división preestablecida, y la primera condición de división preestablecida se utiliza para indicar si se debe restringir que el primer nodo se divida en un modo de división objetivo; si el modo de división que corresponde al primer nodo no se divide de forma adicional, analizar el flujo de bits para obtener información de codificación del primer nodo; y decodificar y reconstruir, con base en la información de codificación del primer nodo, una unidad de codificación que corresponde al primer nodo, para obtener una imagen que corresponde a los datos de imagen.
