Image data compression method and device and readable storage medium

The invention provides an image data compression method and device and a readable storage medium. The image data compression method comprises the following steps: acquiring an original matrix of an input original image; assigning a compressed hidden space dimension through an original image channel, and initializing the initial hidden space feature matrix to obtain a low-dimensional hidden feature matrix; initializing related bias attributes of the original image data; obtaining a reconstruction matrix of the image data by using the low-dimensional hidden feature matrix and the related bias attribute; using the reconstruction matrix and the original matrix to update a low-dimensional hidden feature matrix and related bias attributes; and storing the updated hidden feature matrix and the updated related bias attributes, and obtaining compressed data of the image data. 本申请提供一种图像数据的压缩方法、装置和可读存储介质。其中，该图像数据的压缩方法，包括获取输入的原始图像的原始矩阵；通过原始图像通道指定压缩的隐空间维度，对初始隐空间特征矩阵进行初始化，得到低维隐特征矩阵；初始化原始图像数据的相关偏置属性；使用所述低维隐特征矩阵及所述相关偏置属性，得到图
