Abstract

At present, the incidence of emergencies in obstetric care environment is gradually increasing, and different obstetric wards often have a variety of situations. Therefore, it can provide great help in clinical medicine to give early warning and plan coping plans according to different situations. This paper studied an obstetrics central surveillance system based on a medical image segmentation algorithm. Images obtained by central obstetrics monitoring are segmented, magnified in detail, and image features are extracted, collated, and trained. The normal distribution rule is used to classify the features, which are included in the feature library of the obstetric central monitoring system. In the gray space of the medical image, the statistical distribution of gray features of the medical image is described by the mixture model of Rayleigh distribution and Gaussian distribution. In the gray space of the medical image, Taylor series expansion is used to describe the linear geometric structure of medicine. The eigenvalues of Hessian matrix are introduced to obtain high-order multiscale features of medicine. The multiscale feature energy function is introduced into Markov random energy objective function to realize medical image segmentation. Compared with other segmentation algorithms, the accuracy and sensitivity of the proposed algorithm are 87.98% and 86.58%, respectively, which can clearly segment small medical features.

摘要

目前,产科护理环境中的突发事件发生率逐渐增加,不同的产科病房通常有多种情况。因此,根据不同情况进行预警并制定应对计划,对临床医学有很大的帮助。本文研究了一种基于医学图像分割算法的产科中央监护系统。对中央产科监测获得的图像进行分割,详细放大,并提取、整理和训练图像特征。使用正态分布规律对特征进行分类,将其包含在产科中央监测系统的特征库中。在医学图像的灰度空间中,通过瑞利分布和高斯分布的混合模型来描述医学图像灰度特征的统计分布。在医学图像的灰度空间中,使用泰勒级数展开来描述医学的线性几何结构。引入海森矩阵的特征值来获取医学的高阶多尺度特征。将多尺度特征能量函数引入到马尔可夫随机能量目标函数中,以实现医学图像分割。与其他分割算法相比,所提出算法的准确性和灵敏度分别为 87.98%和 86.58%,能够清晰地分割小的医学特征。
