摘　　要：针对眼底视网膜提取过程存在光照不均、噪声干扰等问题,采用包括光照均衡、图像增强、图像分割、二值化处理、最大类间方差法提取血管图像等预处理操作,解决图像光照不均、对象物呈球状分布、视网膜血管的分割难以达到理想分割效果等困难,提取包括深层次血管在内的完整眼底视网膜图像,达到较好效果。The presence of uneven illumination, noise and other issues, including the use of illumination equalization, image enhancement, image segmentation, binary processing, Otsu extracted blood vessel image preprocessing operation to solve the uneven illumination for retinal image extraction process, the object spherical distribution, retinal vascular segmentation segmentation effect is difficult to achieve ideal difficult, and ultimately extracted include deep retinal blood vessels, including a complete picture. We achieve better results.
