中文摘要 | 中西舌診電腦化的研究是必然的發展趨勢,但是在影像擷取的過程中必須注意環 境的控制,才能保證舌診影像的準確與真實性。在舌診研究上,為了避免失真,必須運用攝 影學上的專業知識。在光源方面,必須考慮色溫、冷光、持續光源、柔和光、以及光的照射 角度等條件,並避免其他光源的干擾。使用的攝影器與舌診影像的品質息息相關,而曝光的 正確與否影響著影像的可信度。外在環境上,首先必須要求光源、舌頭與相機的距離固定, 使環境能統一。其次,為了避免外來光源或物體所產生的反射光線造成的干擾,建議在黑幕 攝影棚內進行舌診攝影工作,並以黑色布幕將可能會造成反光的物件隔開。此外,伸舌姿勢 對舌頭表現造成嚴重影響,而使資料產生可信度上的疑慮,因此教導受試者正確的伸舌姿勢 ,是件非常重要的工作。 |
英文摘要 | Computer-aided analysis of tongue images is a trend in the contempotary study of tongue diagnosis. In order to capture valid tongue images, both environmenttal control and professional knowledge in photography are essential. On the aspect of lighting, variables such as color temperature, cold light, uninterrupted light, soft light, and projective angle of light should be taken into consideration. Resolution of a picture is dependent on the quality of the instrument used and the number of pixels in the picture. The actual exposure, which is determined by aperture and speed, may affect the reliability of the picture. Furthermore, the environment in which the photography of tongue image takes place should be uniform and stable. The prime aspect is that the light source, tongue, and camera should be aligned at a fixed distance. All photographic activities should be undertaken in a shrouded workshop to avoid interfering light source or reflection originating from objects such as the protruding tongue. Finally, as the way of tongue protrusion can affect the quality of images, instructing patients to protrude their tongues properly is also important. |
