The Control Changeable Factor About The Digital Image Of Tongue And Observation Of It Research On The Usage Of Spleen Stomach Deficiency And Excess Syndrome

The research is aimed at objectively controlling the influencing factors of digital tongue image to obtain the real image of the observed tongue and connect to TCM syndrome.Syndrome is a specific concept in TCM,which briefly includes the characteristic of a disease and corresponding state of the organism.It also concludes the location and nature of a disease in the course of its development and gives instruction to tcm doctor in prescribing medicine.The depth of recognition and the correctness of judgment towards syndrome decide the therapeutic effect of TCM.However,the inheritance of TCM relies on the abstract description of Chinese character,the profound meaning is only known by few people.Tongue diagnosis is a distinguishing feature in Syndrome differentiation system of TCM,and tongue is one of the significant observing indicators of one' s health state.The objectivising research of tongue never stops and has made progress in modern study with the development of science and technology through these years.Digital image technology(the universal phraseology "digital" is used in following paragraphs) plays a more and more important role in the application of tongue image objectifivising researches. Predecessors have gradually found an application method to solve many tough problems in digital area.The previous researches focus on the process of producing an image that is to output the image ESP processed from a series of signals by reflecting lights through camera lens.But the influence to the image itself is seldom mentioned.Therefore,how to establish a comparatively objective method on the basis of controlling these changeable values as well as obtain images for sustainable use is the key point of this research.The research contains aspects as follows.1.The Literature ResearchFor a long time the predecessors have researched into tongue objectification in various ways in many fields and also gained certain achievements.Especially in the recent decade,with the rising up of the digital technology,the control of various changeable values as well as the operation in tongue image objectification becomes more convenient.Tongue objectification has gradually made long-term progress in this field.At present tongue image objectification research involves various fields,such as the standard observation pattern,color space,tongue image automatic diagnosis software.The research scope is wide and involves many subjects and specialties.The discussion of tongue image objectification research is comprehensive.2.The Changeable Values During the Digital Tongue Image Catching ProcessThe light or the color temperature in the environment influences the digital tongue image catching process,besides,there are other factors which influences this process.This essay specifically discusses all kinds of changeable values in two divisions according to image catching process.2.1 The analysis of Changeable Values During the Digital Tongue Image Catching ProcessThe main influence of shooting environment is light source and color temperature,so this essay introduces and uses the Commission International de l'Edairage(CIE) standard illumination and observation condition.As the main tool of catching image,a camera' s function is the key factor Of influencing image,so it is necessary to know the categorization,structure and function of a camera as well as the camera lens.Besides,because it is digital image,so the storage pattern,which also has some effect on,the tongue image will be discussed either. 2.2 The analysis of Changeable Values in image ProcessThe later stage of tongue image process is mainly influenced by software; however,the display of the image color mostly depends on color management in the software.Color management emphasizes the choice of color space and the present color space includes:RGB,CMY,1931 CIE XYZ,CIE Lab,HSB,sRGB etc.The display of the image should go through input equipment(camera,image editing software) and output equipment(monitor,print machine,projection machine,etc).For different color space used in different equipment will influence the consistency of color,so color rectification aims at unifying the same color space to rectify and reduce the interference of validity of the tongue image by those originally existing influencing factor in the environment and the camera itself.3.The choice of Changeable Values control in digital tongue image3.1 The choice of the environment light source3.1.1 D65,D55 standard light sourceAs it is said above the light in environment can interfere the display of tongue color in eolourometry as well as the color differentiation of human vision.Therefore,according to the CIE this research compares D65,D55 in luminance test,illuminating scope test and chromomeric index D65 standard light source:use PHILIPS electronic spiral-styled compacted fluorescent light set which inserts the top light by Jiamei light decoration and electrical equipment factory and add an occluder on the edge of the light.D55 standard light source:use the professional optical fiber standard luminescence light, which is produced,by Guanjun photographic accessory factory as light source. (use the name of Guanjun uminescence light in following paragraphs )3.1.2 ResultGuanjun uminescence light is prior to PHILIPS electronic spiral-styled compacted fluorescent light in shutter speed,Ra and patient' s degree of comfort.Therefore,the former one is chosen as the standard light source in this research. 3.2 The White balance and color reducing research of different cameras within the same brand3.2.1 MethodUsing two cameras to respectively picture one piece of paper and GretagMacbeth24 color checker disk on the wall according to the step of auto white balance and hand-motion white balance,then directly use the JPG file by Nikon Coolpix 4300.When comes to Nikon D70,first picture according to the above steps and then edit images with PHOTOSHOP in RAW form,in the end compare the above two.3.2.2 ResultAfter white balance test of both auto and hand-motion and GretagMacbetb24 colored checker disk test Nikon Coolpix 4300,Nikon D70,compare real white color and 24-colored color- rectifying disk,obvious chromatism is exist only by naked eye while in Nikon D70 there' s almost no chromatism after adjusted by PHOTOSHOP.3.3 DiscussionAccording to the results,there' scbromatism in the images only set WHITE BALANCE in the camera while images adjusted by PHOTOSHOP with RAW form can relatively satisfy this condition.4.Clinic research4.1 MethodIn this research,we observe 30 patients diagnosed as stomach depress and stomachache with damp-heat in spleen and stomach syndrome,28 patients with spleen deficiency syndrome and 27 patient with in coordination between the liver and stomach syndrome.Choose optical fiber luminescence light as light source in specially made dark room,set WHITE BALANCE with Kodak Graycard as exposure rectification.Ask the patients not to eat anything before taking picture or at least 2hrs before taking picture that morning.The camera should stay on patient' s normal line and set the standard picturing area by themselves,fill the blanks in the form of syndrome and physical sign.Do colourometry analysis toward the later stage tongue images with PhotoShop CS and compare the changes of color space of CMY,HSB,Lab in patients' tongue images among three groups.4.2 Result4.2.1 Body of the tongueThe redness of the body of the tongue from dark to light are:damp-heat in spleen and stomach group,incoordination between the liver and stomach group, spleen deficiency group.It shows that it is basically the same between colourometry analysis and naked-eye observation on the observation of the body of the tongue.4.2.2 The coating of the tongueThe coating of the tongue shows that the damp-heat in spleen and stomach group appears offset to yellow vector compared to the other two groups and there' s no statistic difference between incoordination between the liver and stomach group and spleen deficiency group,it shows that it is basically the same between colourometry analysis and naked-eye observation on the observation of the coating of the tongue.5.ConclusionAccording to the results of clinical study the image-making intervention method in this essay can basically recover the real tongue state and it has feasibility both in observing index of tongue state changing in clinical therapeutic effect and teaching application.
