Video data decoding, comprising: acquiring an image bit stream; acquiring a feature bit stream indicating a residual feature set obtained by subtracting a second feature set detected from encoded image data generated by encoding the original image data from a first feature set detected from the original image data; retrieving a decoded set of features from the decoded image bitstream; and recovering a first feature set indicating features detected in the input image data according to the decoded feature set and a residual feature set obtained by decoding the feature bit stream. 视频数据解码，包括：获取图像比特流；获取特征比特流，特征比特流指示残差特征集，残差特征集是通过从原始图像数据中检测到的第一特征集中减去从原始图像数据通过编码生成的编码图像数据中检测到的第二特征集而获得的；从解码的图像比特流中，检索解码的特征集；以及根据解码的特征集与从特征比特流解码获取的残差特征集，恢复指示输入图像数据中检测的特征的第一特征集。
