On Automated Tongue Image Segmentation in Chinese Medicine

چکیده
Automated tongue image segmentation in Chinese medicine is difficult due to two special factors: (1) There are a lot of pathological details on the surface of tongue, which have a large influence on edge extraction; (2) The shapes of tongue bodies captured from various diseases or persons are quite different, so they are impossible to be properly described by a predefined deformable template. To address these problems, in this paper, we propose an original technique based on the combination of a bielliptical deformable template and an active contour model, namely Bi-Elliptical Deformable Contour (BEDC). Applying our approach to clinical tongue images, the experimental results indicate that it is superior over both traditional DT (Deformable Templates) and ACM (Active Contour Model or Snakes) with respect to stability and veracity.

Background: Brain tissue segmentation for delineation of 3D anatomical structures from magnetic resonance (MR) images can be used for neuro-degenerative disorders, characterizing morphological differences between subjects based on volumetric analysis of gray matter (GM), white matter (WM) and cerebrospinal fluid (CSF), but only if the obtained segmentation results are correct. Due to image arti...

BACKGROUND Visual inspection for tongue analysis is a diagnostic method in traditional Chinese medicine (TCM). Owing to the variations in tongue features, such as color, texture, coating, and shape, it is difficult to precisely extract the tongue region in images. This study aims to quantitatively evaluate tongue diagnosis via automatic tongue segmentation. METHODS Experiments were conducted ...
