Paper Abstract

Gestational sac (GS) diameters are commonly measured by routine ultrasound in early pregnancy. However, manually searching for the standardized plane of GS (SPGS) and measuring the diameters are time-consuming. In this paper, we develop a three-stage automatic solution for this procedure. In order to precisely and efficiently locate the position of GS in each frame, a coarse to fine GS detection scheme based on AdaBoost algorithm is explored. Then, an efficient method based on local context information is introduced to reduce the false positives (FP) generated by the above detection process. Finally, a database (DB) guided spectral segmentation is proposed to separate GS region from the background for further diameters measurement. Experiments carried out on 31 videos show that by using the proposed methods, the number of SPGS searching error is only one, and the average measurement error is 0.059 for the length diameters and 0.083 for the depth diameters.
