Embodiment 1

[0042] refer to figure 1 , figure 1 This is a flow chart of the method for processing art painting images in this embodiment. In this embodiment, the method includes:

[0043] S1, obtain the original image information of art painting, and convert it into a YUV channel image; the art painting image is obtained based on image scanning; the original image information includes the original image and the user ID;

[0044] S2, extract the Y channel vector according to the original YUV channel image, and generate the first image based on the Y channel vector of the odd-numbered columns and even-numbered rows of the image;

[0045] S3, set an encryption key X, generate a random number n, and perform encryption on each pixel x of the first image in turn to obtain c, thereby generating an encrypted second image;

[0046] Among them, the encryption formula is:

[0047]

[0048] in, The value is 255;

[0049] S4, covering the odd-numbered columns and even-numbered rows of pixels ...

Abstract

The invention discloses a method and a device for processing an image of an art painting. By acquiring the original image information of the art painting and converting it into a YUV channel image; the art painting image is obtained based on image scanning; the original image information includes the original image and the user ID; Extract the Y channel vector from the channel image, and generate a first image based on the Y channel vector of the odd-numbered columns and even-numbered rows of the image; encrypt the first image in turn to generate an encrypted second image; cover the encrypted second image with the original YUV The Y channel vector of odd-numbered columns and even-numbered rows in the channel image is used to generate an encrypted Y-channel image, and based on the encrypted Y-channel image and the UV-channel image of the original YUV-channel image, an encrypted art painting image is generated; and for the user The ID opens the corresponding encrypted information, so that the encrypted artwork image does not affect the electronic viewing effect and ensures the formation of encrypted information and ensures security.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a method and a device for processing art painting images. Background technique [0002] At the artistic level, painting is the act of using a surface as a support and adding color to it. Examples of those surfaces are paper, canvas, wood, glass, lacquer or concrete. At the level of artistic terminology, the meaning of painting also includes the use of this artistic behavior plus graphics, composition and other aesthetic methods to achieve the concept and meaning that the practitioner wishes to express. [0003] In the prior art, excellent paintings are generally scanned to form an electronic version. Specifically, it is generally by laying the manuscript to be scanned face down on the glass plate of the scanner. The manuscript can be a text manuscript or a drawing photo; then After starting the scanner driver, the movable light source installed inside the scanner star...
