研究目的:

本课题拟构建基于机器学习技术的阴道分娩出血量识别工具,通过采集阴道分娩过程中沾染不同出血量的敷料图像,建立出血面积图像训练集;使用机器学习算法和分类器对图像特征进行提取和分类,并在决策级进行概率融合,实现出血量的准确、即时测量。进一步通过AI软件与人工评估出血量的两种方法,对其性能进行测试和评价。  

Objectives of Study:

This protocol aims at developing a Blood Loss Quantification System in vaginal delivery based on machine learning, including the following phases: a. establishing an image training set with materials (e.g. gauze) contaminated by different volumes of blood through the vaginal delivery process; b. using machine learning algorithm to analyze and extract image features; c. using two classifiers to classify the features of image collected, and carry out probability fusion at the decision-making level to achieve accurate and real-time measurement of blood loss. Furthermore, AI software and manual evaluation were compared for blood loss quantification to test and evaluate its performance.
