Image processing method, device and equipment and storage medium

The invention provides an image processing method, device and equipment and a storage medium. The method comprises the following steps: determining a quaternion matrix corresponding to each frame of image in multiple frames of images, wherein the multiple frames of images comprise a first frame of image and a second frame of image; processing the quaternion matrix corresponding to the first frameimage to obtain a first amplitude and a first phase of the first frame image; processing the quaternion matrix corresponding to the second frame image to obtain a second amplitude and a second phase corresponding to the second frame image; and taking the first amplitude and the second amplitude as a ciphertext of the multi-frame image, and generating a key of the multi-frame image according to thefirst phase and the second phase. According to the invention, the first amplitude, the first phase, the second amplitude and the second phase are quickly determined, and the secret key of the multi-frame image is generated ac
