The invention discloses an approximate reversible image translation method based on joint interframe coding and embedding. According to the image translation method, inter-frame coding is performed on a pseudo video composed of a reconstructed source image based on a generative adversarial network and a source image, and a generated coding bit stream is reversibly embedded into a translation image, so that the translation image can be inversely transformed into the reconstructed source image approximately reversibly while the source image is transformed into the translation image. According to the image translation method, the defect that reversibility cannot be guaranteed by an existing image translation method is overcome, an approximately reversible image translation technical framework is constructed, and the image quality of a reconstructed source image in image translation is improved.
Description
technical field [0001] The invention relates to the technical field of image coding, in particular to an approximately reversible image translation method based on joint interframe coding and embedding. Background technique [0002] Image translation based on generative adversarial networks can transform source images in the source domain to translated images in the target domain. Also, the translated image can be inversely transformed into a reconstructed source image. Image translation has played an important role in areas such as content transformation, image style transfer, and image saliency detection. However, existing image translation methods based on generative adversarial networks cannot achieve reversible image translation, that is, there is an irreversible distortion between the reconstructed source image and the source image, which limits the application of image translation to a certain extent. Contents of the invention [0003] The purpose of the present i...
