针对水下低照度环境下光线衰减导致的色彩失真和人工光源导致的光照不均2个退化问题,本文提出一种基于色彩校正和亮度估计的水下低照度图像增强网络,称为LUcobe。LUcobe由色彩校正和亮度估计2个子网络组成。色彩校正子网络通过双色彩空间并结合注意力机制,提取最具辨别力的色彩特征,自适应地集成和突出显示。亮度估计子网络利用编解码器结构结合空洞卷积对图像亮度进行全局估计。最后,将亮度估计和色彩校正子网络的输出在通道选择模块进行结合,实现图像增强。实验结果表明:LUcobe能够有效改善水下低照度图像的不均匀光照和色彩偏差问题,与多种水下图像增强方法相比,在视觉效果和客观评价指标(PSNR,SSIM,MS-SSIM,MSE)上均取得更好的效果。

目的探讨晚期产后出血伴子宫动静脉瘘的临床表现、诊断、治疗及预后。方法对浙江大学医学院附属妇产科医院2018年1月至2022年5月期间收治的病理诊断明确为晚期产后出血伴子宫动静脉瘘的11例患者的临床资料进行分析。结果11例患者中,8例有2次及以上妊娠史(72.7%);9例有宫腔操作史(81.8%)。11例患者临床表现多样,产后发生出血时间在其终止妊娠后8~66(31.2±20.1)d,阴道流血呈现出持续性、反复性和突发性。盆腔血管造影下均可见明显病灶。11例均行双侧子宫动脉栓塞术,阴道流血在术后3~6d得到控制。随访中,3例患者因哺乳月经尚未复潮,4例在术后1~4个月月经规律复潮;1例盆腔炎治疗中,月经未复潮;3例患者失访。结论宫腔操作史与获得性子宫动静脉瘘密切相关,阴道流血是常见症状,但缺乏特异性。临床工作应综合考虑患者临床表现、病情发展、个人因素等,早期识别,给予个体化的治疗方案。
