Fig. 2 is a kind of design diagram of the special scenes generation method of the semantic control of fusion of the present invention.
Specific implementation mode
Below by specific implementation mode, technical scheme of the present invention will be described in further detail.
As depicted in figs. 1 and 2, the special scenes generation method of the semantic control of a kind of fusion, includes the following steps:
Step 1 crawls several article figures and multiple different special scenes pictures for including the article from shopping website;
Step 2, according to different attribute tags are made in special scenes picture the characteristics of special scenes, the label is two The semantic label of binary form;By special scenes picture cutting handle after, obtain training sample, training sample include article figure, The special scenes figure comprising the article corresponding with article figure and the label for describing the scene;
Step 3, structure fight network by the condition production that arbiter and generator form;
Step 4, by article figure and label together as input, be input in generator, generate label described in it is specific Scene graph;
Step 5, the special scenes figure comprising article are as target scene figure, described in the label generated by generator Special scenes figure, target scene figure, article figure and label are input in arbiter together, arbiter by condition fight network into Row model training;
Pending ware figure and the scene wanted are inputted trained model by step 6 in tag form It can be obtained corresponding scene image.
Specifically, in step 3, the production confrontation network is GAN models, the generator of the production confrontation network It is expressed asWherein, y is target scene image area, and x is original input picture, and l is target scene image area Label,For special scenes figure described in label;
In the method for the present invention, each input images of items corresponds to pairs of a target scene image area y and label l, G is allow accurately to learn to generate special scenes.Arbiter study needs true picture with image classification, generator is generated Association's deception arbiter, and arbiter generates probability distribution in input images of items and label, can specify label, realizes The generation of semanteme control generator.The target of generator is that original goods image is converted to the real scene figure described by label Picture, therefore the data set of training sample is provided as one group of respective image (x, y, l), wherein x is input images of items, y It is corresponding target scene image, l is target scene image area label.
The cost function of use condition GAN loses as the antagonism of algorithm model, which is a minimum pole Big double zero-sum game:
Wherein, D is arbiter, and G is generator.
The first item of function shows that arbiter keeps object function as big as possible, and judges when inputting real scene image It is true picture.The Section 2 of function indicates that G (x, y, l) is as small as possible in the image that input generates, and therefore, loses letter Several values is relatively large, and generator, which cheats arbiter and is mistakenly considered arbiter while input is true picture, to be attempted it It is identified as fault image, two models of function are played until reaching Nash Equilibrium, make generator study to the semanteme of label Feature, and be mapped with images of items.
Network is fought using the production of GAN models, generator inputs the original image of aiming field scene, target area image With label as conditional-variable, while generating false special scenes, target area image and aiming field label and being replicated in input And splice with input picture.Generator then attempts from input picture and provides and rebuild new scene in original domain label, and attempts The special scenes that cannot be distinguished with real scene are generated, make to be not easy to be distinguished by arbiter.The two during fighting game, The scene that generator generates is more and more true to nature, and arbiter distinguishes real scene image and pseudo- scene image is further difficult, to real Now trained purpose.
Overall structure of the present invention is simple, reasonable design, using condition GAN as model framework.In order to realize semantic control Function, algorithm model can receive the training data of multiple fields, and only use a generator and learn all available areas Between mapping, this algorithm model does not learn fixed generation (for example, only from clothes to positive model) instead of, by article Image and target information learn the object in input picture being flexibly generated corresponding scene as input.By using Label indicates domain information, in the training process, generates aiming field label at random, training pattern is converted to input picture Aiming field converts the input into any desired scene output in the training stage to realize through semantic control domain label, than Such as input the model for generating that front is stood, hand takes packet, hand to hang down, one model met the requirements for including input clothes of output.
An article figure is inputted, the reasonable scene for including the article is generated.Which overcome two big difficulties, are multiple domain first Generation, followed by generation are not present in inputting and rational scene.For the first situation, the present invention is by the label of training sample It indicates in vector form, and corresponding with input picture, target scene, forms mapping, by the training process, generating at random Input picture is neatly converted to aiming field by one aiming field label, training pattern.By doing so, in the rank using model Duan Shixian inputs different labels by semantic control domain label for same input picture, you can obtains different fields Scape realizes the generation of multiple domain.For the second situation, the present invention provides target scene image in the training stage and describes this The label of scape fights the mapping of e-learning between the two by production, and image is mapped with the text of label, In training process, generator acquires the graphical representation of text, and arbiter identifies true picture and generates image, rich by fighting It plays chess, generator generates human eye and can not distinguish true and false special scenes image.
The invention algorithm model structure is simplified, is trained conveniently, is operated steadily, reliably, portable preferable, can be a variety of It is used in special scenes.
Finally it should be noted that:The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof;To the greatest extent The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that:Still It can modify to the specific implementation mode of the present invention or equivalent replacement is carried out to some technical characteristics;Without departing from this hair The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
