This paper proposes a mobile system for real-time fetal heart rate (FHR) monitoring and fetal distress detection. In the proposed system, FHR values are collected using machine vision techniques and analyzed using a pattern matching approach. When a fetal distress is detected, a medical alarm will automatically notify medical experts through a mobile GSM network. Through the proposed system, not only a pregnant woman can track the healthy status of her baby, but also medical experts can allocate medical resources in time. The implementation result shows that the developed mobile system can be a helpful application for medical management.
