Automatic Tongue Feature ExtractionHsu, Yu-Cheng 06 July 2010 (has links)
In recent years, Chinese medicine in the medical profession in the West triggered a wave of new wave. Chinese medicine is based on four examinations which are listening and smelling examination, inquiry, and palpation to diagnose the patient. Tongue diagnosis is also the first of four diagnostic. The result of tongue diagnosis is based on features of tongue which are diagnosed by doctor. Observation of the tongue focuses on the tongue phenomenon which is structured by the shape of the tongue, and the substance of the tongue, and the coating of the tongue. Pathology of the tongue-shaped includes the medium, fat, lean and crooked, etc. In Pathology of the tongue-substanced, tongue color includes pale, closed to pale, reddish, red, dark red, dark purple, also have some features about ecchymosis, breaken line, tooth mark, and red dot. Pathology for the coating of the tongue includes white, yellow, black, greasy, thick, thin, peeling, or no, etc. Clinically, doctors mostly rely on their own knowledge and experience when determining major lesions of a patient by observing the coloration, overall modalities, and volume of salivary on different parts of the tongue. As a result, the diagnosis tends to be limited by knowledge, experience, train of thought, and diagnostic techniques.The subjective determination is likely to be affected by the doctor¡¦s color sensitivity and interpretation.Different doctors may come to drastically different judgments on the same tongue presentation with little overlap. Therefore, it is important to develop scientific methods that can help doctors diagnose based on standardized differentiation procedures and render reliable diagnoses in order to enhance the clinical application value of Chinese Medicine.The computerized automatic capture of characteristics shown on the images of the surface.At first, the captured image achieves brightness and color correction by brightness calibration and color calibration. Then, the original tongue images go through HSI color space conversion, detection of the control points inside and outside the surface of the tongue, curve smoothness modification and active contour model to capture images of the tongue. After that, the tongue shape, tongue fur, tongue body, and body fluid are captured from the image of the tongue.

Automatic Tongue Diagnosis SystemHsu, Cheng-chun 28 July 2009 (has links)
The core of diagnosis in Chinese Medicine is ¡§pattern identification/syndrome differentiation and treatment¡¨ with inspection, listening and smelling examination, inquiry, and palpation as the bases. Tongue diagnosis tops the four diagnoses and hence is crucial to the inspection diagnosis in Chinese Medicine. Clinically, doctors mostly rely on their own knowledge and experience when determining major lesions of a patient by observing the coloration, overall modalities, and volume of salivary on different parts of the tongue. As a result, the diagnosis tends to be limited by knowledge, experience, train of thought, and diagnostic techniques.The subjective determination is likely to be affected by the doctor¡¦s color sensitivity and interpretation.Different doctors may come to drastically different judgments on the same tongue presentation with little overlap. Therefore, it is important to develop scientific methods that can help doctors diagnose based on standardized differentiation procedures and render reliable diagnoses in order to enhance the clinical application value of Chinese Medicine.The computerized automatic capture of characteristics shown on the images of the surface and the back of the tongue comprises breakup of the tongue image and capture of the tongue characteristics.The original tongue images first go through HSI color space conversion, detection of the control points inside and outside the surface of the tongue, curve smoothness modification and active contour model to capture images of the tongue. After that, the tongue shape, tongue fur, tongue body, and body fluid are captured from the breakup image of the tongue.

The Study on The Agreement Between Automatic Tongue Diagnosis System and Traditional Chinese Medicine PractitionersLu, Chun-Hung 25 July 2011 (has links)
Tongue diagnosis is a unique method of diagnosis practiced in traditional Chinese medicine and an important tool in diagnosing diseases before determining proper methods of cures and treatment. In the traditional clinical practice, tongue diagnosis depends solely on the personal knowledge and experience of the practitioner, thereby lacking in objectivity and quantification. Consequently, an automatic tongue diagnosis system (ATDS) has been developed to provide practitioners with objective data and assist them in reaching diagnoses. To prove the system¡¦s stability in clinical application, this study employs 20 sets of tongue images, taken 10 minutes apart from 20 patients with possible variations in lighting, and the length, shape and angle of extruding tongue. The features extracted by the ATDS for each set of tongue images are compared to investigate the intra-agreement of ATDS, and two sessions of tongue diagnosis questionnaires to investigate the intra-agreement of doctors with consensus (DC) and doctors without consensus(DWC),and the inter-agreement between ATDS, DC and DWC, and the inter- agreement among DC and DWC.
And this study also investigate the improvement of agreement by DWC after a training process.
