Description

A kind of tongue fur constitution recognition methods perceived based on deep neural network and complexity
Technical field
The present invention relates to the tongue fur constitution knowledges of image recognition, data mining technology and traditional Chinese medical science field in computer realm Not, and in particular to a kind of tongue fur constitution recognition methods perceived based on deep neural network and complexity.
Background technology
In China, tcm constitution theory sees China Shanxi generation earliest《37 biographies the 7th of Shanxi books》One book passes through Prolonged development and abundant, it is established that perfect tcm constitution theoretical system.On middle Biography of Medical Figures, constitution is described as in people The congenital and day after tomorrow day in life process is assigned to the form to be formed, and is the general performance of physiological function and psychological condition.《Chinese medicine body Qualitative classification and criterion》Definition:Tcm constitution refers in human vital process, in native endowment and acquired basis On be formed by morphosis, physiological function and psychological condition various aspects synthesis, metastable intrinsic speciality;It is that the mankind exist The human body personal characteristics adaptable with nature, social environment formed in growth, growth course.The classification for studying constitution, must Extensive comparative analysis must be carried out to complicated phenomenon of constitution, then screen classification, hold the constitution difference rule and body of individual Matter feature.《The classification of 9 kinds of basic constitution type in TCM and its diagnosis statement foundation》In conjunction with clinical observation and ancient times and modern times Tcm constitution is divided into gentle matter, deficiency of vital energy matter, deficiency of yang matter, deficiency of Yin matter, phlegm wet matter, damp and hot matter, the stasis of blood by the related understanding of classification of TCM constitution 9 kinds of fundamental types such as blood matter, obstruction of the circulation of vital energy matter, special official report matter, comprehensively reflect somatotypes.Traditional classification of TCM constitution relies primarily on each The characteristics of constitution, is screened, and is screened one by one, what main criterion was put into effect with reference to 2009 years《Traditional Chinese Medicine Constitution Classification with Judgement》.For example, deficiency of yang matter is mainly shown as fears cold, hands and feet being not warm usually, hot drink preference food, lassitude, sweet tea is light fat tender, deeptensepulse Late;Deficiency of Yin matter, which is mainly shown as, defends feverishness in palms and soles, dryness of the mouth and throat, and nose is micro- dry, and cool drink is hard and dry, red tongue with a little fluid, and arteries and veins is thin Number;It is that skin of face grease is more that phlegm wet matter, which is mainly cashed, hidrosis and glutinous, uncomfortable in chest, abundant expectoration, sticky and greasy in mouth or sweet tea, preference for fat and sweet food sweet tea Glutinous, tongue is greasy, slippery.
Lingual diagnosis is that traditional Chinese medical science field is important and unique content, is one of the important content of observation and diagnosis.Lingual diagnosis is by Chinese medicine Clinical workers is used for observing body interior physiology and pathological change at least 3000.Experienced doctor of traditional Chinese medicine is mainly with the naked eye Come information such as color, texture, the forms of observing tongue to judge the physical condition of patient.Tongue is the seedling of the heart, is waited except spleen, tongue It is given birth to by stomach Qi.Internal organs are the collateral of heart meridian system tongue sheet by the be connected important visitor of tcm diagnosis disease of passages through which vital energy circulates and tongue, the few the moon of foot Arteries and veins hold tongue sheet under the arm, the train of thought tongue sheet of the moon of fainting enough, the lunar arteries and veins of foot connects tongue sheet, dissipates sublingual, therefore internal organs lesion, can be in tongue nature and tongue fur On reflect, lingual diagnosis is mainly examined the form of tongue nature and tongue fur, color and luster, is moisturized, and judges the property of disease, patient's condition with this Shallow depth, the prosperity and decline of qi and blood, the profit and loss of body fluid and internal organs actual situation etc..
Computer vision is an important research direction in computer realm, and target detection and image recognition are computers Two vital tasks in vision, with the rapid development of deep learning, target detection also achieves huge with image recognition Progress.Deep learning is a kind of method carrying out representative learning based on data in machine learning, it is by combining low-level image feature shape It is indicated at abstract high level.Its essence is the multi-layer perception (MLP)s for including multiple hidden layers, learn to arrive data automatically by reverse conduction Character representation, to promote the accuracy rate of classification.In machine learning, the performance of learning algorithm depends on its parameter and instruction Practice data.However, the emphasis of most of algorithm development is all adjustment model parameter, without the number for going to consider to be used to training pattern According to.It goes to consider a problem from the angle of data, considers the complexity of sample in individual level, understand data by the original of mistake classification Cause, to promote the accuracy rate of grader.The relationship between tongue fur feature and constitution is excavated using artificial intelligence, is provided for patient Convenient, fast and accurate constitution identification, alleviates medical pressure, additionally it is possible to develop Traditional Chinese Medicine.
