The compression for disclosing code stream for spatial domain is compressed using newest video compression standard HEVC, can be compressed to original
The 10 of beginning video data-2。
In terms of training constraint, this example uses a kind of the way of restraint of associated losses function, associated losses function packet
Containing two loss functions.The distribution distance of reconstruction image and original image in one constraints graph 1 of loss function minimizes reconstruction image
Mean square error with original image is apart from (Mean Square Error), so that the pixel distance of the two is the smaller the better;Lose letter
The distribution distance of encrypted image and original image in several two constraints graphs 1, so that the distribution distance of encrypted image and original image is got over
Big better, which carries out constrained learning by the way of a kind of Cooperative Study.The application defines an arbiter
For differentiating encrypted image at a distance from original image.The arbiter includes three-layer coil lamination and two layers of full articulamentum, encryption figure
Picture or original image input arbiter, and arbiter exports a scalar value.Be divided into two stages in training process, generation phase and
Differentiation stage, two stages pass through neural network encoder, neural network decoder and arbiter, unlike, it generates
Stage only updates the network parameter of neural network encoder and neural network decoder, and the differentiation stage only updates the network of arbiter
Parameter.Two stages, that is, arbiter was when inputting original image, the scalar value of output using identical collaboration loss function
As close possible to 1, for arbiter when inputting encrypted image, the scalar value of output is as close possible to 0.The collaboration instruction that the application proposes
White silk is a kind of mode of effective distribution distance for maximizing two pictures.
Fig. 3 is to utilize this result for constraining in and being tested on facial image.It can be seen that encrypted image is seen not completely
