(3) it is directed to processing system
Processing system is also used to execute following methods, to realize the purpose for obtaining clear video:
S ' 100, the video that the video camera is converted to is obtained;
S ' 200, determine in the video the corresponding cavity position of each frame image and by each frame image according to
Readability classifies to obtain clear image and blurred picture corresponding to the intracorporal different parts of the chamber;
It will be appreciated that including two kinds of classification in step S ' 200, one is divide cavity position belonging to image
Class, one is divide the image into clear image and blurred picture.Both no sequencings of classifying, for example, can be first to figure
As affiliated cavity position is classified, then the image at each position is divided into clear image and blurred picture, detailed process is as follows:
S ' 2001a, using preset position disaggregated model by the video each frame image and default tag library in not
Image with cavity position compares, with the corresponding cavity position of frame image each in the determination video;
Wherein, position disaggregated model can use pattern classification network A lexNet, GoogleNet or other models.Mark
The standard picture at each position in cavity is stored in label library.
S ' 2002a, determine that each cavity position is corresponding each in the video using preset two classifier of clarity
Frame image is the probability of clear image;If the probability is greater than preset value, it is determined that the frame image is clear image, is otherwise determined
The frame image is blurred picture.
Wherein, two classifier of clarity uses convolutional neural networks, the last layer in the structure of the convolutional neural networks
For a full articulamentum, after image is inputted the convolutional neural networks, which can export a range in [0,1]
Between probability value, when the probability value be greater than preset value, then the image can be classified as clear image, when the probability value is lower than or waits
In preset value, then the image can be classified as blurred picture.
It will be appreciated that convolutional neural networks (Convolutional Neural Network, CNN) are a kind of feedforward minds
Through network, its artificial neuron can respond the surrounding cells in a part of coverage area, have for large-scale image procossing
Outstanding performance, it can specifically include convolutional layer (convolutional layer) and pond layer (pooling layer).
It will be appreciated that so-called clear image and blurred picture are opposite concepts, it is by image as clear figure
The probability of picture compared with preset value and determination, wherein the size of preset value and the line of demarcation of clear image and blurred picture have
It closes, if preset value is larger, otherwise it can be considered as fuzzy graph that illustrating that only clarity is higher, which just can be considered as clear image,
Picture.
For example, first by step S ' 2001a by each frame image in video be divided into m (m be inside cavity position number
Amount) a file, the corresponding image in a cavity position is stored in each file, it then will by step S ' 1022a
Image in each file is finely divided, and confirms that it belongs to clear image or blurred picture.
It is, of course, also possible to first divide the image into clear image and blurred picture, then cavity position belonging to image is carried out
Classification, detailed process is as follows:
S ' 2001b, preset two classifier of clarity is used to determine that each frame image is clear image in the video
Probability;If the probability is greater than preset value, it is determined that the frame image is clear image, otherwise determines that the frame image is fuzzy graph
Picture;
S ' 2002b, using preset position disaggregated model by each frame clear image and each frame blurred picture respectively with
The image of different cavity body region compares in default tag library, with each frame clear image of determination and each frame blurred picture point
Not corresponding cavity position.
It will be appreciated that the explanation in relation to content can refer to step S ' 2001a and S ' in S ' 2001b and S ' 2002b
2002a。
For example, each frame image in video two files-are divided by step S ' 2001a first clearly to scheme
As file and blurred picture file, then determined corresponding to the image in each file by step S ' 2001b
Cavity position.
Both the above mode can determine the corresponding clear image in each position and blurred picture, but latter approach
Processing speed it is quicker so that the real-time of the process flow of entire method is much better.
S ' 300, the corresponding blurred picture in each position is carried out at deblurring using generation confrontation network trained in advance
Reason obtains corresponding de-blurred image;
That is, fighting network by generation trained in advance carries out deblurring processing to each blurred picture, obtain
To the corresponding de-blurred image of this blurred picture.
Wherein, the training process for generating confrontation network includes the following steps:
A1, the first training sample for concentrating preset training sample are separately input into few two different convolutional Neural nets
Deblurring processing is carried out in network, obtains at least two frame de-blurred images;Wherein, first training sample is blurred picture;
Wherein, at least two different convolutional neural networks can be selected from numerous convolutional neural networks, for example, super
Resolution ratio convolutional neural networks (referred to as SRCNN), efficient sub-pix convolutional neural networks (ESPCN) and be based on Unified Network
(unet) at least two in convolutional neural networks.It is, of course, also possible to select other kinds of convolutional neural networks.
For example, as shown in figure 4, the first training sample is inputted SRCNN, ESPCN respectively and based on the convolutional Neural of unet
In network, SRCNN can export corresponding de-blurred image, ESPCN is right after carrying out deblurring processing to the first training sample
After first training sample carries out deblurring processing, corresponding de-blurred image can be exported, the convolutional neural networks based on unet exist
After carrying out deblurring processing to the first training sample, corresponding de-blurred image can be exported.
A2, fusion treatment is carried out at least two frame de-blurred images, obtains that first training sample is corresponding to be gone
Blurred picture;
Due to passing through multiple available de-blurred images of step A1, it is therefore desirable to which to this, multiple are gone by the way of certain
Blurred picture carries out fusion treatment, obtains a de-blurred image as the final corresponding de-blurred image of the first training sample.
Wherein, there are many modes of fusion treatment, for example, being melted by the way of weighting to multiple de-blurred images
It closes.For another example to the mode that multiple de-blurred images are aligned one by one, obtain include multi-layer image stitching image, then
Multi-layer image is projected in a certain coordinate system, multiple images are obtained, then this multiple image is carried out by the way of weighting
Fusion.
In the case where the quantity of convolutional neural networks is 3, three different convolutional neural networks are to first instruction
Practice after sample carries out deblurring processing and obtains the first de-blurred image, the second de-blurred image and third de-blurred image, it is above-mentioned
The amalgamation mode of latter citing may include steps of:
A21, the second de-blurred image C2 is directed to the first splicing that the first de-blurred image C1 generates two layers
Image M1;
A22, the third de-blurred image C3 is directed at the second spliced map that the first stitching image M1 generates three layers
As M2;
A23, described three layers of the second stitching image M2 is projected in global coordinate system, obtains three projected images;
A24, the overlapping region of three images is carried out by pixel fusion using weigthed sums approach, obtains first instruction
Practice the corresponding de-blurred image of sample.
It is, of course, also possible to which there are other modes carries out fusion treatment to image, obtains the first training sample and finally correspond to
De-blurred image.
A3, the probability that the corresponding de-blurred image of first training sample is clear image is calculated, and according to the probability
Judge whether the corresponding de-blurred image of first training sample is clear image:
If so, the training process for generating confrontation network terminates;
Otherwise, the second training sample corresponding de-blurred image of first training sample and the training sample concentrated
Originally training is compared, obtains the corresponding de-blurred image of first training sample relative to the total of second training sample
Penalty values, according to the total losses value to the deblurring parameter of described at least two different convolutional neural networks and/or described
Fusion parameters used by fusion treatment are adjusted, and return step A1.
Wherein, second training sample is clear image and second training sample and first training sample pair
Answer the intracorporal same area of the chamber.
Wherein, the calculating process of total losses value may include following process:
A31, the corresponding deblurring figure of first training sample is calculated separately using at least two different loss functions
As the penalty values relative to second training sample;
A32, at least two penalty values that described at least two different loss functions are calculated are added up, is obtained
Total losses value of the corresponding de-blurred image of first training sample relative to second training sample.
For example, loss function is denoted as d_loss1, d_loss2, d_loss3 respectively, utilizes these three loss functions point
It does not calculate penalty values of the corresponding de-blurred image of the first training sample relative to second training sample, then will obtain
Three penalty values summations, obtain total losses value.
For example, arbiter to deblurring treated probability that image differentiated between [0,1], if probability
Less than determined threshold value, then the clear image gap for representing de-blurred image relative to same position is larger, cannot be by the first training sample
This corresponding de-blurred image regards as clear image, thus need in deblurring treatment process deblurring parameter and/or
Fusion parameters in fusion process are adjusted, and to reduce total losses value, are then gone using deblurring parameter adjusted
Fuzzy Processing and/or use fusion parameters adjusted carry out fusion treatment and obtain the corresponding deblurring of the first training sample again
Image, and then judge whether the de-blurred image is clear image again constantly recycles, until obtained de-blurred image can be with
Until being considered clear image
Wherein, as shown in figure 5, generate confrontation network may include two sub-networks-deblurring sub-network and differentiate sub-network,
Deblurring sub-network therein can execute above-mentioned steps A1 and step A2, differentiate that sub-network can execute above-mentioned steps A3 and step
Rapid A4, the process of parameter adjustment are also to adjust the process of the network parameter in deblurring sub-network.Confrontation network is generated as one
Kind deep learning model is in recent years for one of the method for unsupervised learning most prospect in complex distributions.Pass through deblurring
Sub-network (be referred to as generate model, Generative Model) and differentiation sub-network (it is referred to as discrimination model,
Discriminative Model) mutual Game Learning, fairly good output result can be generated.Deblurring sub-network and differentiation
Sub-network might not all be neural network, it is only necessary to be that can be fitted the corresponding function generated and differentiate.But practical application
In generally use deep neural network as deblurring sub-network and differentiate sub-network, a good generation confrontation network needs
Have good training method, otherwise may due to neural network model freedom and cause to export undesirable.
S ' 400, it is synthesized each frame clear image and de-blurred image to obtain the clear of the cavity sequentially in time
Clear video, and the clear video is shown.
Since de-blurred image is clear image, sequentially in time by de-blurred image and original clear image
After synthesis, the corresponding clear video of original video can be obtained, the clear video be by the fuzzy frame in original video into
Become articulating frame after the certain processing of row, so that entire video is all than more visible.
Here, processing system removes the blurred picture in the collected video of cavity mirror system by generating confrontation network
Then the clear image obtained after original clear image and deblurring processing is carried out synthesizing sequentially in time by Fuzzy Processing
