Abstract

A tongue coating evaluation method for WTCI(Winkel Tongue Coating Index) is proposed in this paper, which is used as the diagnostic criteria in the tongue diagnosis. This method uses the color channel analysis and tongue coating extraction from the ultraviolet tongue image. Proposed method analyzes the histogram distribution of the respective color channel for extracting a tongue coating, and performs the verification test from the selected color channel in the tongue coating extraction. Also, Objectivity of the tongue diagnostic criteria is verified by the artificial sample and real-tongue image experiments. In order to evaluate the performance of the proposed Computerized Assistant WTCI Evaluation method, after verifying a measurement accuracy by using the artificial sample images, and applying to the various real-tongue image of subjects. As a result, the proposed WTCI method is very successful.

본 논문에서는 한방 의료의 설진에 있어서 객관적인 진단 지표의 생성을 위해 자외선 혀 영상 채널 분석과 설태 검출에 의한 WTCI(Winkel Tongue Coating Index) 설태 평가 방법을 제안한다. 제안한 방법은 설태 영역 검출을 위하여 자외선 광원에 의해 생성된 혀 영상의 칼라 모델별 각 색상 채널의 히스토그램을 분석한다. 그리고 선택된 혀 영상 채널을 이용하여 설태 검출에서의 성능 검증 실험을 수행한다. 또한 WTCI 설태 지표 생성을 위한 테스트 샘플과 실영상 검증 실험을 실시하여 설진 지표의 객관성을 검증한다. 제안한 컴퓨터 지원 WTCI 설태 평가 방법의 성능 평가를 위해서 샘플 영상을 이용하여 계산의 정확성을 검증하고, 다양한 실제 피실험자의 혀 영상에 적용한 결과 성공적인 결과를 보였다.
