Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawings and the specific embodiments Describe the present invention.
A kind of cell atypia automatic grading method tactful based on degree of depth study and combination of the present invention, including following step Rapid:
Step 1, the choosing of training sample:
Training sample is to build from original data, and original data are all by the clinic of specialty pathology knowledge Doctor was marked, and program can be marked in pathological image according to these experts and randomly select foursquare image fritter, Wherein the length of side of these fritters is 256 pixels.Program can build corresponding to each point respectively according to the quantity of image resolution ratio The training sample set of resolution.
Fig. 1 is cell atypia degree schematic diagram;Wherein (a) in Fig. 1 be corresponding nucleus atypia grade be the group of 1 Knit pathological image block, (b) in Fig. 1 be corresponding nucleus atypia grade be the histopathology image block of 2, (c) be corresponding carefully Karyon atypia grade is the histopathology image block of 3.
Step 2, the training of degree of depth convolutional neural networks:
Use the sample training convolutional neural networks that step 1 is chosen as shown in Figure 3.Degree of depth convolutional neural networks is as initially The one of artificial nerve network model feedforward neural network, obtained significant progress in recent years, particularly at image Reason and speech recognition aspect.As trainable multitiered network structure, the convolution stage includes convolutional layer, nonlinear transformation layer, under Sample level i.e. pond layer.
Convolutional layer extracts the feature of image by convolution kernel, and this is concept based on local receptor field.Each convolution kernel Extract the special characteristic of all positions on input feature vector figure, it is achieved the weights on same input feature vector figure are shared.In order to extract Features different on input feature vector figure just uses different convolution kernels to carry out convolution operation.Convolutional layer is extracted by nonlinear transformation layer Feature carry out nonlinear mapping.Traditional convolutional neural networks uses saturation nonlinearity function to carry out nonlinear mapping Sigmoid, tanh or softsign.Commonly used unsaturation nonlinear function in the convolutional neural networks being recently proposed ReLU.Model carries out back-propagation gradient decline when, ReLU is than traditional saturation nonlinearity function convergence speed more Hurry up, during such training network, iteration time can go up many soon.Pond layer is that each characteristic pattern is carried out independent operation, makes at present With more be to use average pond or maximum two kinds of pondization operation.Average pond is calculating pixel in the window of selected field Average, and maximum pond is the maximum calculating selected field window, and the step-length that general window translates is 1.Characteristic pattern leads to After crossing pondization operation, the resolution reduction of characteristic pattern but remains effective feature.Meanwhile, pondization has also reached a dimensionality reduction Purpose.After feature extraction completes, connect full articulamentum and grader by after the output characteristic figure of last layer.
Convolutional neural networks use original image pixel directly as the input of network, with traditional image recognition algorithm Different, it is to avoid the extraction of complicated manual features;Weights share the quantity that can reduce weights, thus reduce the calculating of network Complexity;The feature that the use of local receptor field makes whole network be observed has translation and rotational invariance.Network Output corresponds directly to classification, and such point-to-point, end-to-end network model is greatly enhanced the precision of identification.
Step 3, use the convolutional neural networks that trained to combine sliding window to process image:
Convolutional neural networks is applied in the middle of cell atypia classification, it is contemplated that the complexity of organizational structure in tissue slice Property, multiformity, spreading all over property and irregularities, use the method for sliding window to travel through whole image.Slider bar selected by utilization, from The upper left side of sectioning image starts, and from left to right, slides the most successively, and the convolutional network model that often slides is all to window Interior image block judges, it is judged that the grade belonging to each window.
Step 4, absolute majority ballot method judges the grade of single resolution hypograph:
Using sliding window technique to process significantly image in step 3, every image can produce a lot of subset, wherein subset Quantity relevant with the step-length of the size of institute altimetric image and slip, volume machine model all can carry out classification to these subsets so that One big width image produces a lot of subset classification results.Absolute majority ballot method is used to determine from the classification results of these subsets Plan goes out the classification results of significantly image.Being mathematically represented as of absolute majority ballot method:
As shown in formula (1),For representing from class mark set C1,C2,C3Prediction in (corresponding respectively to scoring correspondence) The class mark C gone outj,Represent in input picture x, be predicted to be class mark CjThe quantity of window;N is class mark set Middle removing class mark CjOther class target quantity;If class mark CjNumber of votes obtained more than half, then be predicted as such mark, H (x) for input figure The final result drawn by absolute majority ballot method as x.
Step 5, under each resolution detection image carry out above operation, obtain each image difference differentiate Classification results under rate.The image of each case in general data comprises the image under three kinds of resolution, and these three is differentiated Rate is 100 times respectively, 200 times and 400 times.So through aforesaid operations, the image of each case can obtain three cell abnormal shapes Property classification results.
The final result of step 6, relative majority ballot method joint decision multiresolution:
The result of multiple resolution of the image of each case, uses relative majority ballot method to obtain the final of each case Result.Relative majority ballot method be prediction who gets the most votes's labelling, if having simultaneously multiple labelling obtain the highest ticket, the most therefrom with Machine chooses one.The voting strategy of relative majority ballot method is:
F ( x ) = C arg max j Σ i = 1 T H i j ( x ) - - - ( 2 )
As shown in formula (2),InFor the result of above-mentioned absolute majority ballot method, F (x) is three The most final grade of classification that under yardstick, occurrence number is most.
For the ease of public understanding technical solution of the present invention, a specific embodiment is given below.
