In embodiments of the present invention, terminal receives and shows the image authentication code obtained based on above-mentioned checking request, should Image authentication code includes the first picture and second picture, which is the picture cut from stylized picture, this first Picture is the remaining picture after cutting off above-mentioned second picture in stylized picture.

Above-mentioned stylization picture is the picture obtained after style converts for generating the original image of image authentication code.

Style transformation can refer to through certain algorithm, and the image in original image is converted into possess certain specific style Image, to generate stylized picture.The style of image is mainly the detail textures passed through in image, the expression way of lines It is embodied with coloring style, so the style conversion of picture is exactly that the texture in original image is converted to certain with coloring style to refer to The style of reference style image is transformed into another input picture by fixed style, for example, a kind of reference picture is selected, Can will be in different illumination, different periods, the photo of Various Seasonal shooting translates into different styles art uply.

Original image obtains the stylized picture of the original image after style converts, and general machine is more difficult by the style Change picture and carries out inverse transformation to obtain original image.

In embodiments of the present invention, the generating mode of above-mentioned image authentication code can use method shown in Fig. 4.Fig. 4 institute It is shown as the generation method flow chart of image authentication code provided in an embodiment of the present invention, as shown in figure 4, this method includes：

Step 401, the original image for generating image authentication code is obtained.

In embodiments of the present invention, original image is pre-stored picture in database, obtains the mode of original image It can be random acquisition, be also possible to according to preset Rule.

Step 402, stylized picture is obtained according to above-mentioned original image.

In embodiments of the present invention, above-mentioned acquisition stylization picture can be under the triggering of checking request, according to original The stylized picture that picture generates in real time is also possible to obtain pre-generated stylized picture according to original image, this is in advance The stylized picture of generation can store in the database.

In embodiments of the present invention, can use depth convolutional neural networks model to original image carry out style transformation with Generate stylized picture.

For example, can include 16 using preparatory trained 19 layers of VGG network (referred to as VGG-19), the VGG network The feature space that convolutional layer and 5 pond layers provide, the convolution kernel size of each convolutional layer is 3, step-length 1, while each There is the nonlinear activation layer of a ReLU behind convolutional layer, treated that output is that image stylization obtains through the function Characteristic pattern.

Style transformation will common image become the style of another style image, basic principle is：It is one given The secondary style image S of picture X and one, finds a picture Y, so that Y is close with X in terms of content, while close with S in style. The content and style of picture can be to be extracted by trained VGG-19 network.

It is that depth convolutional neural networks model is used to carry out style transformation to original image to generate stylization as shown in Figure 5 The exemplary diagram of picture, wherein picture pointed by arrow is original image, and the picture of arrow root is that style picture is used for wind For the sample of case transformation with reference to figure, the picture below arrow is the stylized picture of depth convolutional neural networks model output, it is seen then that The content of the stylization picture is close with original image, and its style is close with style picture.

VGG-19 network trained for one, using picture A as input, so that it may several groups characteristic pattern is obtained, this The structure of a little characteristic patterns is [H, W, C], wherein H and W respectively represents the height and width of characteristic pattern, and C represents the number of characteristic pattern, should [H, W, C] can represent the content of A, the Multidimensional numerical F (X) that structure is [H*W, C] be obtained after deformation, to the multidimensional number Group F (X) asks gram matrix G=Gram (F (X)), the textural characteristics of available X, i.e. style.

After the extracting mode for defining content and style, image style convert the problem of can by way of optimization solution Certainly.Assuming that Y is according to the image of the content of X and the synthesis of the style of S, the content error of Y and X are：

The style error of Y and S is：

To which global error is：

L_A=α L_C+β·L_S

Wherein, α is content proportion in global error, and β is style proportion in global error, α and β value The different representatives of size are different to the emphasis of content and style.

The algorithm of style transformation can be based on iteration optimization, specially：1) random initializtion image Y；2) whole mistake is found out Poor L_A；3) each point pixel value of Y is adjusted according to gradient descent algorithm；If 4) L_AConvergence is less than preset threshold, then stops Otherwise only iteration continues the 2) step.

Since depth convolutional neural networks usually have at least millions of parameters, so complicated parameter transformation to think The stylized picture obtained after style is converted carries out inverse transformation and is difficult to realize with obtaining original image.

Step 403, local picture is cut from stylized picture as second picture.
