1. A method for picture decoding, comprising:
receiving bitstream data and parsing the bitstream data to obtain a Coding Tree Unit (CTU) corresponding to the bitstream data;
enabling a preset refreshing mode, the preset refreshing mode being configured to perform overlapping decoding on the CUS;
parsing a node of a layer in the CTU to determine a leaf parameter corresponding to the node, the leaf parameter being configured to determine whether to partition the node;
performing detection processing on the node according to the leaf parameter to obtain a detection result;
continuing to acquire a node of a next layer corresponding to the CTU according to the detection result;
determine a state parameter and a flag parameter corresponding to the node, the state parameter being indicative of whether the node supports a refreshing process, and the flag parameter being indicative of whether the node enables the refreshing process;
continuing to perform detection processing on the node of the next layer, and obtaining data of all Coding Units (CUs) corresponding to the CTU; and
generating a decoded picture corresponding to the bitstream data according to the node and the data of all CUs.
