Example Embodiment
[0040] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, giving a detailed embodiment and a specific operating process, but the scope of protection of the present invention is not limited to the following embodiments.
[0041]The present embodiment provides an image compression method based on discrete Gaussian hybrid superatural and Mask, comprising the following steps: preprocessing the compressed image to obtain a preprocessed image; extracting the feature map of the preprocessed image, while based on the spatial feature information of the preprocessed image, generating a Mask value, the feature map and the Mask value are treated by point multiplication, to obtain a hidden variable representation; using a plurality of Gaussian distributions to extract the distribution of the hidden variable representat...
