摘要
针对中医自动化舌诊中的舌图像分割问题,提出一种融合多颜色分量的舌图像阈值分割算法。对RGB颜色空间中的蓝色和红色分量执行阈值分割,确定舌图像中的人脸区域;对HSI颜色空间中的色调分量执行变换,在变换后的色调分量上执行阈值分割,以获得包含真实舌体与上嘴唇的初始目标区域;对初始目标区域对应的红色通道执行阈值分割,得到舌根和嘴唇之间的间隙区域;利用间隙区域剔除掉初始目标区域中的上嘴唇,获得最终舌体分割结果。仿真实验表明:该算法较大程度地改善了舌图像分割的精度。
To solve the problem of tongue image segmentation in TCM automatic tongue diagnosis,we proposed a threshold segmentation algorithm of tongue image based on multi-color components.Threshold segmentation of blue and red components in RGB color space was performed to determine the face area in tongue image.The hue component in HSI color space was transformed,and the threshold segmentation was performed on the transformed hue component to obtain the initial target area including the real tongue body and upper lip.Threshold segmentation was performed on the red channel corresponding to the initial target area to obtain the gap between the tongue root and the lip.The upper lip in the initial target area was removed by using the gap area,and the final result of tongue segmentation was obtained.The simulation results show that the proposed algorithm greatly improves the accuracy of tongue image segmentation.
