Specifically, the method comprises the following steps: the method for generating the countermeasure network subspace decoupling and generating and editing specifically comprises the following steps:

step S10, selecting a network and generating a picture;

specifically, in this embodiment, a generation countermeasure network (only a generator is needed) that is trained and capable of generating high-quality pictures is first selected.

Further, the picture is correspondingly generated in the generation network inside the generation countermeasure network through the generation countermeasure network.

Step S20, obtaining image labels through a pre-trained classifier, and inputting the generated pictures into a preset attribute classification network to obtain attribute label data of the pictures;

in this embodiment, a semantic classifier corresponding to the image space and the attribute needs to be selected to obtain the semantic label of the picture. Specifically, a trained semantic classifier f is selected according to the image space of the training data of the selected generator and the semantic space required to be decoupled.

And then obtaining an image label through a pre-trained classifier, and inputting the generated picture into a preset attribute classification network to obtain attribute label data of the picture.

Specifically, in this embodiment, the tag data L of the picture in step S21 is obtained, and a gaussian model fitting is then used to fit the semantic subspace of the hidden space, where the specific implementation process is as follows:

firstly, a single Gaussian model is constructed, specifically, a Gaussian distribution model P (z) is respectively used for each type of semantics, and a normalized likelihood function | is constructed.

Further, a loss function is constructed, specifically, a hidden variable semantic subspace is preliminarily fitted by using the gaussian model, and the normalized likelihood function value | | | p (z) | | | and the label data L obtained in the step S21 are used as a mean square error to obtain the loss function.

Further, the gaussian model is optimized, specifically, the gaussian model is optimized through the loss function and by using an Adam algorithm, so that a set of gaussian model groups with certain semantic information in a hidden space can be obtained.

Step S41, the obtained Gaussian model group is used as an initial component to construct a first Gaussian mixture model; constructing an L1 loss function by normalizing a likelihood function and a mean square error loss function of the label data and by sampling the label data and a sampling coefficient of a picture sampled and reconstructed from the first Gaussian mixture model; performing Adam algorithm optimization on the first Gaussian mixture model through the L1 loss function to obtain a second Gaussian mixture model; and each semantic subspace in the hidden space is in one-to-one correspondence through each Gaussian component in the second Gaussian mixture model.

Further, a loss function is constructed, specifically, an L1 loss function is constructed by using the loss function of the mean square error of the normalized likelihood function and the label data L acquired in step S31, and by using the label data and the sampled coefficients of the picture sampled and reconstructed from the above-mentioned first gaussian mixture model.

Further, a gaussian mixture model is optimized, specifically, the L1 loss function is used for the first gaussian mixture model, and the first gaussian mixture model is optimized by the Adam algorithm to obtain a second gaussian mixture model.

And finally, performing semantic decoupling, specifically, respectively corresponding each Gaussian component in the acquired second Gaussian mixture model to each semantic subspace in the hidden space.

Step S51, collecting attribute control vectors zs in each obtained Gaussian component of the second Gaussian mixture model; interpolating the first code of the picture generated by any generator and the zs to obtain a second code; and inputting the second code into the generator to obtain a picture edited by continuous attributes according to the interpolation proportion of the zs.

Specifically, first, sampling of the attribute variable is performed, and the vector zs is controlled by using the sampling attribute in each gaussian component in the second gaussian mixture model obtained in step S41.

Further, performing controllable editing, specifically, for any one of the pictures generated by the generator, interpolating the first code corresponding to the picture and the zs to obtain a second code, and inputting the second code into the generator, then obtaining the picture with the edited attribute according to the interpolation ratio of the zs.

The semantic attributes of smiling, gender, Liuhai and age of the face picture can be edited by the method, and the decoupling degree between the semantic attributes is large when the method is used for semantic editing, namely when some attribute is edited, only the target attribute of the picture is changed, and other attributes are not changed.

It should be noted that, the method provided by the second embodiment of the present invention, which implements the same principle and produces some technical effects as the first embodiment, can refer to the corresponding contents in the first embodiment for the sake of brief description, where this embodiment is not mentioned.
