Embodiment 1

[0042] refer to figure 1 , figure 1 It is a flow chart of the method for processing an image of an art painting in this embodiment, and in this embodiment, the method includes:

[0043] S1. Obtain the original image information of the 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 to which it belongs;

[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 column and even row of the image;

[0045] S3, setting an encryption key X, generating a random number n, and sequentially performing encryption on each pixel x of the first image 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, first merging the encrypted second image...

Abstract

The invention discloses an art painting image processing method and device, and the method comprises the steps: obtaining the original image information of art painting, and converting the original image information into a YUV channel image; the art painting image is obtained based on image scanning; the original image information comprises an original image and an affiliated user ID; extracting Y channel vectors according to the original YUV channel image, and generating a first image based on the Y channel vectors of odd columns and even rows of the image; and encrypting to generate a second image, combining the second image with the Y channel vectors of the even columns and the odd rows of the original image to generate an encrypted Y channel image, and combining the encrypted Y channel image with the UV channel image of the original image to generate an encrypted image. More random encryption algorithm processing is performed by selecting local rows and columns of the Y-channel image, and the corresponding encryption information is opened for the user ID, so that the encrypted art work image does not affect the electronic viewing effect, and the formation of the encryption information is ensured.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to an art painting image processing method and device. Background technique [0002] Painting, on an artistic level, is the act of applying color to a surface as a support, such as paper, canvas, wood, glass, lacquer, or concrete. At the level of artistic terms, the meaning of painting also includes the use of this artistic act coupled with graphics, composition and other aesthetic methods to achieve the concept and meaning that the practitioner hopes to express. [0003] In the prior art, excellent paintings are generally scanned to form an electronic version. Specifically, it generally spreads the original to be scanned face-down on the glass plate of the scanner. The original can be a text manuscript or a photo of a drawing; and then After starting the scanner driver, the movable light source installed inside the scanner starts to scan the original; in order to illumi...
