英文摘要：

A fast automatic IUD （intra-uterine device） recognition algorithm for the ultrasound uterus images was proposed. Components of the algorithm inclucled an automatic ultrasound uterus image segmentation algorithm and a specific pattern recognition framework. The performance of the algorithm was demonstrated by using 719 ultrasound uterus images, and the experimental results show that the average computation time is 527 milliseconds per frame. The recognition accuracy of the uterus image with or without IUD is 81.1% or 94. 7% respectively.
