Embodiment Construction
[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0041] The present embodiment provides an image compression method based on discrete Gaussian mixture super prior and Mask, comprising the following steps: preprocessing the image to be compressed to obtain a preprocessed image; extracting the feature map of the preprocessed image, and simultaneously based on the Preprocess the spatial feature information of the image to generate a Mask value, and perform dot product processing on the feature map and the Mask value to obtain a hidden variable representation; use multiple Gaussian distributions to extract the distribution of hidden vari...
