The video image information that main frame is gathered to web camera is handled and analyzed including moving object detection and right Moving target is classified.The image sequence of video camera recording is divided automatically using machine vision and the method for video analysis Analysis, realizes positioning, the identification to target in dynamic scene, and analyzes and judge the behavior of target on this basis, draws to figure As the understanding and the explanation to objective scene of content implication, so as to instruct and planning action.Carried out referring to Fig. 3 and Fig. 4 It is described in detail.
First, it is sequence of video images that main frame, which will obtain collection sample changeover, and carries out image preprocessing to it, is treated Detection image, then carries out moving object detection to image to be detected.Herein on the basis of studying target detection technique, carry A kind of background modeling method based on Gaussianmixture model is gone out, has been established using the method for statistics based on color and color gradient Background model, and background model is updated in real time, finally both background models is considered target is carried out Effective detection.The problems such as algorithm preferably solves the extraction of background model, renewal, background perturbation, extraneous illumination variation. Key step is as follows:
1) background modeling:Automatically the advantage that background model is background difference algorithm is set up, can be different according to scene, learning The habit stage inputs training video image to algorithm, is trained by certain time, is automatically learned the parameter of background model;
2) sport foreground is detected:As soon as often carrying out two field picture, present image and background model are carried out difference, i.e., with background mould Type is matched.It can allow the size of algorithm dynamic adjusted threshold according to scene, be prevented effectively from missing inspection and the flase drop of moving region, The robustness of algorithm is improved simultaneously;
3) post-processing:Result to background difference is further processed, and obtains more accurate complete moving target Region, such as removes shade;
4) target detection:Moving target scope is confined in original image;
5) background model updates:According to background difference and the result of target detection, determine whether background model needs renewal, Algorithm is adapted to the change of various complex scenes, improve the accuracy rate of detection, it is to have influence on background subtraction to select suitable turnover rate Divide the key of effect.
Using moving target at background model identification, and feature extraction is made to moving target, carried out according to the feature of extraction Moving object classification.Assorting process is divided into offline training process and online decision process, offline training process needs pair The model of foundation is trained, and can be applied to online decision process.
The present invention carries out pattern-recognition using SVMs, judges whether it is dangerous abnormal image, choose stabilization and It can reflect that the feature of object essence, as input vector, filters out smaller moving target, eliminate noise, effectively reduce the instruction of model Practice the time.
SVMs is a new technology in data mining, is to solve Machine Learning Problems by means of optimal method New tool.It is based on Statistical Learning Theory, and its structural risk minimization avoids " cross and learn " phenomenon of neutral net, And with good generalization ability.It is minimum etc. real that supporting vector function preferably solves small sample, non-linear, high dimension drawn game portion Border problem.When handling nonlinear problem, it is translated into the linear problem in higher dimensional space first, then with a core letter Count to replace the inner product operation in higher dimensional space, so as to dexterously solve complicated calculations problem.SVM is wide in the application of each field It is general, it is adapted in pattern-recognition build grader, its basic thought is:A hyperplane is constructed by two different set point Open, as shown in Figure 3.Sample can be divided for two classes in plane, the task of machine learning is to find straight line, can not only be two Class sample is separated, and ensures that class interval is maximum.So-called class interval refers to from this straight line into two class samples nearest sample This apart from sum, and these minimum distance samples are SVMs.Complicated classification problem can first pass through non-linear The input space is transformed to a higher dimensional space by mapping, then obtains optimal classification surface in the higher dimensional space.SVMs The schematic diagram of classification is as shown in Figure 3.For given training set:T={ (x1,y1),…,(xn,yn)}∈(X×Y)n, wherein, xi ∈ X=Rn,yi∈ Y={ 1, -1 } (i=1,2 ..., n), xiVector is characterized, there is straight line g (x)=wTX+b makes all yi =-1 point falls in g (x)<0 one side, all yi=+1 point falls in g (x)>0 one side.And maximum apart from both sides border It is known as optimal hyperlane.Standard supporting vector grader now is:
yi[w·xi+ b] -1 >=0i=1,2 ..., N (1)
Supporting hyperplane is to the distance of optimal hyperlane:D=1/ | | w | |, the distance between two Optimal Separating Hyperplanes Margin is two times of d, i.e.,:Margin=2d=2/ | | w | |.It is known as the problem of optimal hyperlane is to solve for:
However, in the case that sample data is complicated and changeable, optimal hyperlane is difficult that all samples are done into one accurately Divide, therefore, introducing relaxation factor ξi, its purpose is to loosen restrictive condition, it is allowed to certain wrong distribution life, then formula (1) sorter model is changed into:
yi[w·xi+b]-1+ξi>=0i=1,2 ..., N (3)
Now, the quadratic programming problem for solving optimal hyperlane is just changed into:
In above formula, c is the punishment parameter of error, wrong point sample proportion and algorithm complex can be traded off, true C value is small in fixed proper subspace represents small to the punishment of experience error, and the complexity of Learning machine is small and empiric risk Value is larger;C takes infinity, then all constraints must all is fulfilled for, it means that training sample must classify exactly.Often Individual proper subspace at least make it that SVM Generalization Abilities are best in the presence of a suitable c.
Sample in Practical Project is often nonlinear, it is therefore desirable to which input space x is passed through into certain Nonlinear MappingA high-dimensional feature space is mapped to, linear optimal separating hyper plane is reconstructed in this space.This mapping is usual Realized with designing the method for kernel function, using different kernel functions with regard to various forms of Nonlinear Support Vector Machines can be obtained. Conventional kernel function has following four type:
(1) linear kernel function:K (x, x ')=(xx ')
(2) Polynomial kernel function:K (x, x ')=((xx ')+1)q
(3) RBF kernel functions:
(4) Sigmoid functions:K (x, x ')=((xx ')+1)q
The sorter model constructed in space after Nonlinear Mapping is as follows:
Now, it is desirable to which the object function of solution is changed into:
In summary, SVM basic thought is exactly that the nonlinear change defined by interior Product function converts the input space To a higher dimensional space, then optimal classification surface is sought in this new space.
The emulation experiment of the present invention is to be carried out based on open source software LIBSVM with MATLAB2016b platforms, and LIBSVM is platform Simple, easy to use and fast and effectively SVM pattern-recognitions and the recurrence that the exploitation such as gulf university professor Lin Zhiren is designed Software kit.The software not only provide it is compiled can Windows serial systems execution file, additionally provide source code, side Just improve, change and applied in other operating systems.
When being trained to grader, the penalty parameter c and nuclear parameter g of its training pattern are (with the σ in kernel function each other It is reciprocal) selection crucial effect is played to the accuracy of classification results, but using net the selection of the two parameters so far more Lattice are searched for and cross-validation method.However, grid search be included in certain scope according to artificially given density it is all Possible parameter combination, then finds out the minimum parameter combination of predicated error as its optimal solution, its amount of calculation is huge again.Intersect Then each subset is trained set checking collection, Jin Erfa by proof method each other again by being N number of subset by training sample random division Existing optimal parameter combination.But due to be every time it is random split training data, therefore the Optimal Parameters obtained every time are also not to the utmost Identical, along with amount of calculation is relatively large, when training samples number increases, search procedure excessively expends the time.Therefore, this hair The bright parameter combination optimal using improved gravitation searching algorithm Automatic-searching, builds optimal decision function so that SVM points The accuracy highest of class, then obtains improved universal gravitation algorithm-support vector machine classifier, i.e. IGSA-SVM graders.
Gravitation searching algorithm (Gravitational Search Algorithms, GSA) is that one kind is come to physics Gravitation in carries out the swarm intelligence optimization method of simulation generation, as a kind of meta-heuristic algorithm, the search in GSA Particle is to act on attracting each other by gravitation between one group of object in space motion, object, and the motion of object follows dynamic Laws of Mechanics.Because gravitational effect can cause objects to be moved towards the maximum object of quality, and the maximum thing of quality Body occupies optimal location, so as to obtain the optimal solution of optimization problem.The algorithm passes through the gravitation phase interaction between object With the shared of optimization information is realized, guiding colony is searched for optimal solution regional implementation.
The present invention proposes a kind of improved gravitation searching algorithm (IGSA).By introducing backward learning strategy, essence English strategy and boundary mutation strategy, make basic gravitation searching algorithm have higher optimization precision and stable Property, tested finally by 13 reference functions, to verify that improved gravitation searching algorithm has preferably optimization property Energy.Support vector machines grader is optimized using improved universal gravitation algorithm IGSA, SVM training moulds can be sought The penalty parameter c of type and nuclear parameter g optimal solution, realization are classified to moving target.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art It may be appreciated other embodiment.
