1. An encoding method, comprising:
generating a segmentation map image indicating a segmentation map of an input image
generating a video stream including an encoded segmentation map image;
generating a feature vector using the input image and the segmentation map image;
generating a feature stream including an encoded feature vector;
generating a reconstructed image using the segmentation map image and the feature vector;
generating a residual image between the reconstructed image and the input image;
generating an encoded residual image by encoding the residual image; and
generating an output stream by performing multiplexing on the video stream and the feature stream,
wherein the encoded segmentation map image is generated by encoding the segmentation map image,
wherein the encoded feature vector is generated by encoding the feature vector,
wherein the output stream includes a residual stream, and
wherein the residual stream includes the encoded residual image.
