| 摘 要： | 为了尽可能多地获取舌下静脉的形态信息,采用近红外舌下静脉图像采集仪获取近红外舌下静脉图像,并提出对应的舌下静脉分割方法.根据所采集到图像的特点,首先使用分水岭法去除舌下静脉周围的舌质背景等干扰信息;然后使用动态灰度阈值法在已获得的有效舌下区域进行二值化,并结合近红外舌下静脉图像的灰度信息确定舌下静脉候选区域;最后根据舌下静脉区域的灰度一致性进行自适应的区域生长,获得舌下静脉轮廓.实验结果表明,该方法能有效地分离舌下静脉与环绕在其周围的舌质背景,并能准确地定位舌下静脉的完整边界.

| Abstract: | In order to acquire more accurate shape information of sublingual vein,a near infrared sublingual vein image acquisition device is employed to capture the near infrared sublingual images,and a corresponding segmentation method of sublingual vein is proposed as well.According to the characteristics of the captured images,at first a watershed-like technique is used for background removal,followed by a dynamic thresholding to binarize the detected effective sublingual region,then candidate sublingual veins reg... |
