1. A neural network based image decoding method comprising:
obtaining intra prediction feature data of a current block from a bitstream;
obtaining intra flow information indicating a reference pixel corresponding to each pixel included in the current block, based on the intra prediction feature data, first neighboring pixels of the current block, and coding context information of the current block;
obtaining a predicted pixel of the current block based on the intra flow information of the current block; and
reconstructing the current block based on the predicted pixel.
