Description
Technical field
The present invention relates to digital pathological image processing technology field more particularly to a kind of liver's tissues based on OTSU threshold value
Pathological image dividing method.
Background technique
Liver cancer (liver cancer) refers to the malignant tumour for betiding liver, including primary carcinoma of liver and metastatic hepatic carcinoma
Two kinds, the liver cancer of the daily theory of people refer to it is mostly be primary carcinoma of liver.Primary carcinoma of liver be clinically the most common malignant tumour it
One, according to recent statistics, the whole world newly sends out liver cancer patient about 600,000 every year, occupies the 5th of malignant tumour.For different
Cancer cell-types, cancer cell diffusion have different effective therapeutic modalities.Currently, being especially most of cancers in clinical diagnosis
In disease diagnosis, by biopsy, fall off with Fine-needle Aspiration Cytology etc., to the living tissue of patient's lesion region
Be sliced the pathological examination results being observed and analyzed under microscopic view and obtained be doctor carry out medical diagnosis on disease it is important according to
It is considered as " goldstandard " of cancer diagnosis according to even final foundation, the diagnosis based on pathological images.
Currently, the diagnosis with pathological picture is mainly manually checked by the doctor of profession, with the day of number of patients
Benefit increases and to the continuous improvement that medical diagnosis on disease accuracy rate requires, and the pathological images quantity for needing to analyze is doubled and redoubled, therefore needs
Increase more personnel, equipment copes with a greater amount of histopathological analysis demands.However the national conditions according to China at this stage,
Experienced doctor's rare numbers, and it is horizontal irregular, pathology department's room level of digital is generally relatively low, and digital pathology equipment is tight
Weight is deficient, this brings great difficulty to the further development of pathological diagnosis.In view of storing the convenience with remote transmission,
Digitlization histopathology image is increasingly taken seriously, it is often more important that, digitlization histopathology image is to introduce intelligence auxiliary
Analysis provides possibility to mitigate doctor's burden, significant to the nervous situation for alleviating medical resource.
Instantly the intelligent assistant analysis means of mainstream include: image characteristics extraction, deep learning model etc., and these are auxiliary
Analysis method is helped to generally require a large amount of data sample.It is to have training samples more as far as possible first by taking deep learning as an example,
The secondary distribution for being to ensure that sample is enough uniform, but actual conditions are possible to be frequently encountered the inadequate situation of sample size, cannot
Meet the training requirement of deep learning model.
Summary of the invention
It is an object of the invention in view of the shortcomings of the prior art, provide it is a kind of design rationally, be able to solve pathological section figure
Excessive and sample size deficiency problem liver's pathological image sample Enhancement Method based on stochastic transformation.
To achieve the above object, the invention adopts the following technical scheme:
A kind of liver's pathological image sample Enhancement Method based on stochastic transformation comprising following steps:
1) block division is carried out to liver's pathological image, obtains several image fritters;
2) stochastic transformation is carried out to each image fritter, forms exptended sample;The stochastic transformation include horizontal mirror image switch,
One or more of vertical mirror overturning, cutting, brightness adjustment, saturation degree adjustment and adjustment of color;
3) exptended sample input deep learning model is trained liver's pathological image, and is carried out pair with liver pathological image
It should enhance, obtain the enhancing sample of liver's pathological image.
Preferably, the size of image fritter described in step 1) is 320*320 pixel.
Preferably, the method for horizontal mirror image switch described in step 2) and vertical mirror overturning are as follows:
If the width of image fritter is width, length height, the former coordinate in image fritter before a certain point transformation is (x0,
y0), transformed coordinate is (x, y), then,
Horizontal mirror image switch needs to meet:
X=width-x0-1
Y=y0;
Vertical mirror overturning, needs to meet:
Preferably, the method for cutting described in step 2) are as follows: keep the resolution ratio of image fritter constant, if image fritter
Width be width, length height, the cutting coefficient of width and length is respectively a and b, then, the image after cutting is wide
Degree is width*a, length height*b.
Preferably, the method for brightness adjustment described in step 2), saturation degree adjustment and adjustment of color are as follows:
HSI is converted by image fritter rgb pixel value, conversion formula is as follows:
Wherein,
Saturation degree component is given by:
Strength component is given by:
The change coefficient of HSI three is both configured to 0.1, the HSI of image fritter is changed into original 0.9 or 1.1 at random
Times, complete the adjustment to the small Block Brightness of image, saturation degree or tone.
To guarantee training up and effectively restraining for deep learning model, needs to acquire a large amount of samples pictures before training and make
Input when for model training, the pathological section figure that doctor can provide under normal conditions marked it is extremely limited, often
It is not able to satisfy the training requirement of deep learning model.
The present invention is built upon using pathological section figure under the background for training deep learning model, and there are two for the background
A problem makes pathological section figure be difficult to be used directly to training pattern: first is that picture is too big, can not be used directly to training pattern, need
It is cut into fritter;Second is that the quantity of slice map is few, so the sample size of directly piecemeal formation is also few, the instruction of model will lead to
White silk is insufficient.
The invention adopts the above technical scheme, by carrying out block division to liver's pathological image, obtains several images
Fritter, and stochastic transformation is carried out to each image fritter, exptended sample is formed, so as to effectively expand original pathology
Sample solves the problems, such as that sample size deficiency and sample distribution are uneven to a certain extent, meets deep learning model full-page proof
The requirement of this amount, can effectively avoid the model trained from over-fitting occur, and the situation of generalization ability deficiency improves assistant analysis
As a result reliability.Before core of the invention is to trained deep learning model is applied to after the progress stochastic transformation of image fritter
Picture pretreatment link in, effectively solves the problems, such as that pathological section figure is excessive and sample size deficiency.
