5 Commonly used tongue geometric features. Reprinted from Wang and Zhang (2013b), with permission from Elsevier 26 2 Tongue Images Acquisition System Design geometric indexes which describe the tongue shape are crucial for diagnosis of several speciﬁc diseases (Maciocia, 2013). Also, other kinds of geometric features, including the width–length ratio, area of the tongue body, and inscribed-circle diameter, are frequently used for medical analysis. Moreover, the thickness of the tongue body is similarly found to be useful to reveal pathological changes of internal organs.

The aim of all steps is to maximize the accuracy and reproducibility of the imaging system. 1 Camera Lens Aperture The apertures of a camera lens need to be ﬁxed to avoid overexposure. Usually, it is achieved by setting the camera response to the largest value of 255 for a perfectly reflecting object (white board). , USA) was ﬁrst imaged by the system, and then, the average value of G channel (〈G〉) of a single or a group of pixels in the acquired images was checked. If it was lower than 255, the aperture needed to be enlarged, otherwise, it needed to be narrowed.

Various types of imaging cameras and lighting sources with diverse imaging characteristics were utilized. Therefore, the quality of the obtained tongue images considerably varies. This kind of inconsistent image representation makes images capture by different devices incompatible and noninterchangeable. Developed algorithms and obtained results based on these captured images would be unstable and inconvincible. Hence, a comprehensive test of the designed system to ensure their accuracy and stability is necessary.
