- 结合CNN与RNN，分别提取图像特征和时间依赖性
- 提升胎儿脑超声视频分析的效率与准确率
- 适合医学影像分析、产前诊断领域研究者
本文提出一种针对胎儿脑部超声视频的关键帧检测新方法。该模型采用复合神经网络架构，融合卷积神经网络（CNN）与循环神经网络（RNN），其中CNN用于提取单帧图像的空间特征，RNN则捕捉视频序列中连续帧之间的时序依赖关系。该方法可提升胎儿脑部超声分析的效率与准确性，有助于实现特定胎儿脑部疾病的早期检测、诊断及治疗规划。
原文摘要 · Abstract (English)
This article presents a novel approach to keyframe detection in ultrasound videos, with a particular focus on fetal brain imaging. The proposed model is a composite neural network architecture that combines a Convolutional Neural Network (CNN) with a Recurrent Neural Network (RNN). The CNN extracts spatial features from individual video frames, while the RNN captures temporal dependencies between consecutive frames within each video sequence. The proposed model may improve the efficiency and accuracy of fetal brain ultrasound analysis, thereby supporting earlier detection, diagnosis, and treatment planning for selected fetal brain conditions.
